Can a baby be born with a negative blood type if both parents have a positive blood type?
and and one from their father, which get passed from generation to generation.... all babies get genes from their parents, who in turn got genes from their parents... -all- of your genes came from your parents, if your parents don't have the gene, you can't get it. (unless you're a mutant)
Hair and skin color are complicated because there are lots of different genes that control it, which is why we have so many shades of colors of hair and skin color. But the Rh factor is simple, just two options + or -. If you are Rh-, then you are - - (one negative came from mom and one from dad). If you are Rh+, then you are either + + or + - (it only takes one positive to make you positive)
If both parents are Rh+ and have mixed genes (+ -), then it is possible that each of them will give the - gene to their child, making the child Rh- (- -). (there is a 25% chance that the child will be Rh- and 75% chance that the child will get a positive from either one or both parents)
If one parent is Rh+ and has 2 positive genes (+ +) then it doesn't matter what the other parent is, all the children will be Rh+ Here is another website that may be able to help ans some quest: http://www.thetech.org/genetics/ask.php?id=114
So, to answer your question. Two Rh+ parents can have an Rh- child..... but the negative still came from the parents.
How do you become a genetic engineer?
1) A good all round education.
2) An ability to get on with others in a team.
3) A sound moral sense -- above all, a scientist has to be concerned with the truth, has to be honest.
4) An ability to love your subject of study/research and show individual initiative.
5) A lively and creative imagination; a flair for problem-solving.
6) A sharp intellect and an ability to think reductionistically, i.e. to consider living things in terms of molecules or objects to be tinkered with to suit human desires.
7) And ability to regard one's chosen living organism as a tool with which to build one's career, provided one respects the basic minimal ethical standards of treatment of the organism (e.g. an animal) imposed by society.
8) Late high school and exam passes to university entrance grades covering Biology, chemistry and mathematics subjects, as well as genetics as part of the biology.
9) An undergraduate education in molecular biology or molecular genetics and a good enough Bachelor of Science degree to qualify for studying for a research degree (Doctor of Philosophy, Ph.D.).
10) A PhD degree based on several (e.g. 3) years of your own original research under the guidance of a supervisor.
11) Some post-doctoral research experience in which you choose a domain of molecular biology to make your own.
12) Practical experience in recombinant DNA techniques can be gained during academic research or through research and development (R&D) in industry.
13) Laboratory technicians including those charged with the care of the living organisms to be genetically modified in many countries often require special training at technical colleges. Some technicians work their way up by coming in with no qualifications and learning on the job.
What is a vector used for in a genetic engineering experiment?
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".
What is the function of genetic material in a virus?
Viruses contain either DNA or RNA as their genetic material. Viruses containing RNA as their genetic material are called retroviruses
The genome of a virus could either be:
- single or double stranded DNA
- single or double stranded RNA
Many scientists think genetic material was composed of protein because?
Protein was originally thought to be the genetic material because of its complexity, protein is made up 20 different amino acids while DNA only consists of four bases. This was logical as the complexity would account for diversity in organisms. But after more research was done it was realized that DNA was actually the genetic material.
Blood gas analysis, also called arterial blood gas (ABG) analysis, is a test which measures the amounts of oxygen and carbon dioxide in the blood, as well as the acidity (pH) of the blood.
Why is genetic engineering important?
- genetic engineering is a way of intentionally going a genetic sequence in DNA so that a particular traits is produced. that what a genetics engineering. but did u know that herb Boyer first transferred DNA from one species to another.so that whats about genetic engineering. Next, i'm going to talk about is that genetcs engineering.it can haelp spociety is humanbeings living and acting together.
Can the genetic material for both plants and animals is DNA?
All living organisms have DNA. They differ subtly, but are about 99% similar.
cellular cloning is the process of making a populaion of cells from a single cell. cellular cloning is the process of making a populaion of cells from a single cell. cellular cloning is the process of making a populaion of cells from a single cell.
How does crossing over affect the genetic diversity of a species?
in crossing over the gens present on chromosomes forms linkage so the character are exchange & thus it lead to recombination of genes that affect genetic diversity
What did Barbara McClintock found out about genetics?
During the 1940s and 1950s, McClintock discovered transposition and used it to show how genes are responsible for turning physical characteristics on or off. She developed theories to explain the repression or expression of genetic information from one generation of maize plants to the next. Hope this helps. Sources: Wikipedia
What are Three ethical questions from modern genetic research?
genetic research will continue to raise ethical questions and much contraversy.Examples of these include:1-Who will have access to this expensive technology?the rich or the poor?2-What are the rights of the dead people ?who should have access to their DNA samples?3- all children are of inestimable value,and it is contrary to their dignity and the dignity of their procreation to be selected, conceived and utilised for the benefit of another4-Ageing,illness and death are parts of human biography and seeking to eliminate them denies human evolution and what the future will bring
AnswerThere are many ethical questions posed feom genetic research. A few might be:Is it right to store unused oocytes in a freezer until needed?Is it right to make transgenic organisms?Is it right for insurance companies to get information on your genetic makeup and charge you more if you have the gene for a particular disease?Is it right to trust DNA fingerprinting?There's 4... that should do.

pea has many sharply ditinct traits each trait has two clear alternative forms e.gseed shap has round or wrinkled phenotype plant hieght was long or short seed colour was yellow or green Mendel called them pair of contrasting trait
What is genetic variation measured with?
Variation of quantative characters such as littersize and lifetime reproductive output. Variation in protein sequence. Variation in the non-coding regions of DNA
What are the arguments for genetic engineering?
Genetic engineering can cause side affects unknown to humans.
And it is messing with nature and the way of human life
Role of microorganisms in genetic engineering?
Add bacteia genes to crop plants can improve plant species :)
What is the genetic structures located within the nucleus called?
In the nucleus of each cell in the human body (excluding gametes [23]) there are 46 chromosomes, these chromosomes consist of lots of different genes that all join up together (A to T, G to C) and each gene has a code for a certain part of your body.
How does studying genetic disorders such as pku help biologist understand normal alleles?
PKU is a genetic disorder that, when untreated, is characterized by mental ... but, in a person with PKU, this enzyme is defective.

What is the difference between Genetic Engineering and Natural Reproduction on plants?
Genetic engineering is when scientists manipulate individual genes within organisms.
EXAMPLE:
Artificially introducing a gene from a jelly fish into a rabbit. the result is a rabbit that glows in the dark under an ultraviolet light source. This is one example.
Natural reproduction is when that organism chooses to mate with another organism. You are not forced, its just natural.
Does DNA replication start at only one place in the DNA?
What do you mean by one area? If by one area you mean does it start at one area then stop and continue on another area then no, DNA replication is continuous and when it takes place it is the most important thing going on in the cell. The cells resources are directed at this process * DNA replication means copying the entire DNA molecule, so it involves the entire molecule, but not all at the same time. In bacteria (prokaryotic cells) replication begins at one point in the molecule and continues all the way round the circular molecule.
Beginning at just one place would take too long in eukaryotic cells; someone has calculated that our longest chromosomes would take about a fortnight to replicate, and we cannot wait that long! So replication begins at a number of sites along the length of the DNA molecule. At each replication site, as the DNA strands are separated there is a bulge in the molecule called a replication bubble. As replication proceeds these bubbles become longer, and eventually they merge into one another and the job is done.
