Laboratory Testing

Yes. A parent either passes their type or the parent doesn't. In your case, your type is B, and you didn't pass this type to your child. The mother doesn't have either the A or the B type. The same goes with the RH.

the adult flies were removed during weeks 2 and 4 so that they weren't accidentally counted as the offspring(when counting how many offsping of each phenotype there are). If they were accidentally counted as the offspring, the data would be biased.

The generally accepted theory is that males determine the sex because males can donate both an X chromosome or Y chromosome, while females can only donate an X chromosome to their offspring :D

RNA is a single-stranded molecule composed of a ribose sugar, a phosphate group, and one of four nitrogenous bases (adenine, guanine, cytosine, or uracil). It plays a key role in gene expression by carrying genetic information from DNA to make proteins through the process of transcription. RNA can exist in various forms such as messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Endospores are dormant, tough, and non-reproductive structures formed by some bacteria to withstand harsh environmental conditions. They allow the bacteria to survive unfavorable conditions like high temperatures, desiccation, and exposure to chemicals or radiation. Endospores can germinate back into active bacterial cells when conditions become suitable again.

On average, males have a higher blood volume than females. This is because males typically have larger body sizes and muscle mass, which require more blood for oxygen transport and nutrient delivery. Additionally, hormonal differences can also affect blood volume in males and females.

It is highly unlikely that someone can alter the results of a DNA test without working at the testing facility or having access to the sample prior to testing. DNA tests are conducted under controlled conditions to ensure accuracy and prevent tampering. Any unauthorized alteration would require inside knowledge or physical access to the testing process, which is typically tightly regulated to maintain integrity.

approximately 40,000 white blood cells can and will fit on the eye of a pin

A white blood cell (WBC) count of 15.4 indicates an elevated number of white blood cells in the body, which can suggest an infection, inflammation, or a possible immune system response. It is important to consult a healthcare provider for further evaluation and diagnosis to determine the underlying cause.

During an autopsy, a forensic pathologist examines a deceased person's body to determine the cause of death. This involves analyzing the internal organs, tissues, and body fluids, as well as taking samples for toxicology analysis. The findings from the autopsy can provide valuable information for legal investigations, medical research, and closure for the deceased person's family.

When your body is dehydrated, cells lose water and essential nutrients necessary for proper functioning. This can lead to decreased cell volume, impaired cellular communication, and reduced energy production. In severe cases, dehydration can cause cells to become damaged and may lead to organ dysfunction.

Most Americans are Rh positive, with around 85% of the population having this blood type. Rh negative blood type is less common in the United States, with around 15% of Americans possessing it.

People with A- blood type are often recommended to eat a diet rich in fruits, vegetables, plant-based proteins, and whole grains. They may benefit from avoiding dairy, red meat, and high-fat foods. It's best to consult a healthcare provider or dietitian for personalized recommendations.

A Basic Metabolic Panel (BMP) typically requires a serum separator tube (SST) or a gel-barrier tube. These tubes are commonly gold or red-striped tops. The gold or red-striped top tube is used to collect a blood sample for various tests, including those in a BMP, which measures basic metabolic markers like glucose, electrolytes, and kidney function.

A B positive child will have B antigen (agglutinogen) in his blood. Since O+ve blood has neither A nor B antigen and A +ve blood does NOT have B antigen, the baby will naturally have no B antigen in his blood. It may be either A or O ; but not B or AB.

Preliminary results are usually available in 24-48 hours, but the final results are allowed to grow for 72 hours, and only after that time is a culture result considered final.

A blood smear is a sample of blood that is spread thinly on a glass slide, stained, and examined under a microscope. It is used to evaluate the number, morphology, and size of different types of blood cells such as red blood cells, white blood cells, and platelets. This test helps in diagnosing various blood disorders and infections.

"C antigen is an antigen in the Rhesus blood grouping system. This blood group system is associated with over 40 antigens which may or may not be present in a someone's blood, determining her or his place in this system. The most famous Rhesus antigen is the D antigen, sometimes called the Rhesus factor, which can cause complications in pregnancy. Blood analysis for C antigen can be performed in a lab which has the serotyping tools necessary to identify the presence of this antigen in the blood. As with some other antigens associated with blood types, the C antigen can create a blood incompatibility which may cause problems during pregnancy or with blood transfusions. If someone does not have this antigen and she or he is exposed to the blood of someone who does, C antibodieswill develop. With the next exposure, a coagulation reaction will occur in the blood. For this reason, it is important to avoid transfusing C positive blood into people who do not have the antigen.Whereas most blood types are determined by red cell antigens that differ by one or two amino acids, the Rh blood group contains the D antigen which differs from th"e C/c and E/e antigens by 35 amino acids. This large difference in amino acids is the reason why the Rh antigens are potent at stimulating an immune response

The person with the O negative blood has an anti-RH antibody in their blood which will make the O positive platelets received coagulate (neutralizing it since the body sees the antigen RH as a foreign substance) which can cause severe problems depending on how much O positive blood is received.

There is no direct conversion between milliliters and centimeters as they are measuring different things (volume and length, respectively). The relationship between them would depend on the dimensions of the object being measured.

Since the mother has an "O" blood type (which is recessive), she can only pass down "O" blood type alleles. This means both children must have at least one "O" allele (whether they express it depends on the allele they inherit from their father). Since the mother is RH positive, she has to have at least one positive allele. It is possible she carries a recessive RH negative allele. (An allele makes up half of your genes: one from dad, one from mom.)

This being said, we can now determine what alleles the children got from the mother and, by process of elimination, what was inherited by the father. The O negative child would have two O alleles, which means the parents must each have had an O allele. The negative allele again is recessive, so for the child to express this, he/she must have gotten a negative allele from both parents. This confirms that the mother has a recessive negative allele, although her blood type is O positive.

Now the B positive child gives us more limitations on what the father could be. The mother would have passed down an O allele to this second child, meaning that the B allele must have come from the father. The positive allele could have come from either the father or the mother (since the mother has a positive and negative allele), so it is undetermined what RH alleles the father completely has.

Since the father must have an O allele to pass down to the first child, a negative allele to pass down to the first child, and a B allele to pass down to the second child, it leaves us with only two possibilities of the father's blood-type:

B positive or B negative.

Hopefully this helps, but do remember that blood type is not completely a reliable way to eliminate a father. Any mutations in the child's genes may have caused him to express an allele that was not from the father, thus a paternity test would still be needed to know for sure. But from what we learn in High School Biology, "B+" and "B-" would be the correct answers in this case and probably follow 90% of the time (I am estimating here.)

Group A blood types have A antibodies attached to their blood cells.

Group B blood types have B antibodies attached to their blood cells.

If you give a group A blood type a transfusion with type B blood, their body will attack the type B blood cells after sensing foreign antibodies.

Since Group O does not have any antibodies attached to the blood cells, you can give it to type A. Type A will not detect foreign antibodies since group O has no antibodies, and therefore, the body will accept the type O blood.

All Medical Answers need confirmation and re-confirmation.

Epithelial cells are the cells your body uses to line tubes, among other things, and the term renal refers to the kidney.

So they are saying that in the urine they found some cells that normally line tubes, but they could tell they weren't from the kidney. This could mean they came from the bladder, the ureters, urethra, or even someplace else.

A haemogram-ESR, or erythrocyte sedimentation rate, is a blood test that measures the rate at which red blood cells settle in a tube over a specific period of time. It is a non-specific indicator of inflammation in the body and can help in diagnosing conditions such as infections, autoimmune diseases, and certain cancers. The results are typically reported in millimeters per hour (mm/hr).

In a basic CBC from the lab there is a test for Lymph, Mono, Eos, and Baso. These are all distinct categories of viral or bacterial infection fighters. Lymph is short for lymphocytes with are responsible for the activities of the immune system. If lymph is high that means there is bacterial, viral or another type of infection invading the body.
