When a recessive gene is inherited from only one parent and a normal gene is inherited from the other parent will the offspring have the condition?
A recessive trait shows up when there is no dominant trait to mask it. For example, say the allele for brown hair is B and for red hair is b. If the father contributes an allele for brown hair and the mother contributes and allele for red hair, the child's phenotype would be Bb and it would have brown hair. However if both parents contributed an allele for red hair, the child's phenotype would be bb and it would have red hair. You can do the same thing for eye color. Say the allele for green eyes is G and the allele for blue eyes is g (I don't know if this is actually correct, but it's just an example). If the father gives the allele for green eyes, G, and the mother gives the allele for blue eyes, g, the child's phenotype is Gg and it has green eyes. However, if both parents contribute alleles for blue eyes, then the child's phenotype is gg and it has blue eyes.

How are sex linked traits inherited?
Sex-linked traits are inherited from the organism's parents.
Can two white people have an albino baby?
Albinism is a recessive trait, meaning that an albino person has the genotype AA, while a person who isn't albino has the trait Aa or AA. Two albino people (AA x AA) will have all albino children. Aa x AA will have a 50% probability of albino children, and 50% normal children who are carriers (Aa). AA x AA will have all normal children who are carriers (Aa). Aa x Aa will have 25% AA (normal/non carriers), 25% AA (albino), and 50% Aa (normal/carriers) offspring. AA x AA will have all normal children who are not carriers (AA).*A person who has the genotype Aa is a carrier because they carry the allele (a) for albinism but they are not albino. The allele (A) is dominant so it covers the (a) allele.
Are apterous wings dominant or recessive?
Apterous wings are typically a recessive trait in insects. This means that an individual must inherit two copies of the apterous allele to exhibit the wingless (apterous) phenotype. If an individual has one copy of the apterous allele and one copy of the dominant allele for normal wings, they will have normal wings.
Hemophilia is a sex linked recessive disorder Mary does not have the disease but both of her brothers do Neither of her parents have the disease What are Marys parents genotypes indicates pr?
Mary's father is normal and has a normal genotype XY while her mother is the carrier of hemophilia and has one X of her genotype infected i.e. she is X*X.
Is albinos genes formed from mutation?
Albino is a rare condition that causes color not to appear in people. You would be albino if your hair and eyebrows were an off white, you were very pale, and in some cases got sunburned easily. If you are concerned for whatever reason, ask someone like your parents or loved one.
When recessive gene for disease is inherited?
Recessive gene alleles are ones for which two copies are required to cause disease. Many people may have one copy and be phenotypically normal (non-diseased). People who have the disease will have gotten one copy from each parent, each of whom may be normal unless they, themselves have two copies.
Is sickle cell disease dominant or recessive?
The disease is recessive, requiring both parents to carry the allele for the disease to be found in the offspring. If one parent has it, the offspring can also be a carrier, but it will be recessive, and the offspring will have normal RBC (red blood cells)
Why aren't somatic mutations passed on to the next generation?
Somatic mutations occur in non-reproductive cells and are not passed on to offspring because they do not affect the germline cells (sperm and eggs) that give rise to the next generation. Only mutations in the germline cells can be inherited by offspring.
Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.

What type of alleles does a person considered a Carrier have?
A person considered a carrier typically has one normal (dominant) allele and one mutated (recessive) allele for a specific gene. This means they do not exhibit symptoms of the genetic condition associated with the recessive allele but can pass the mutated allele to their offspring. For example, in autosomal recessive disorders, carriers are asymptomatic but can potentially have affected children if their partner is also a carrier.
What is an individual who has a recessive disease causing allele at a particular gene on one chromosome and a normal allele at that gene on the other chromosome?
An individual with a recessive disease-causing allele on one chromosome and a normal allele on the other chromosome is referred to as a heterozygote for that gene. Since the disease is recessive, the normal allele typically masks the effects of the recessive allele, meaning the individual usually does not exhibit symptoms of the disease. However, they can still pass the recessive allele to their offspring.
An individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
They are a carrier of the disease but do not show any symptoms because they have one normal allele that can compensate for the recessive disease-causing allele. If they have children with a partner who is also a carrier, there is a chance their offspring may inherit two copies of the disease-causing allele and develop the disease.
Color blindness is an X-linked recessive trait A color-blind man has a daughter with normal color vision She mates with a male who has normal color vision What is the expected phenotypic ratio of t?
The expected phenotypic ratio for their offspring is 1:1, with a 50% chance of being color blind (male with the X-linked recessive trait) and a 50% chance of having normal color vision. This is because the daughter is a carrier of the recessive allele, which can be passed on to her offspring regardless of the father's color vision status.
What is thalesemmia entermedia?
Thalassemia Intermedia is a recessive trait inherited disease of the red blood cells. In thalassemia, the genetic defect results in reduced rate of synthesis of normal hemoglobin chains.
Does the Carriers of genetic diseases who do not have the disease themselves have recessive genes for the disorders?
Yes, carriers of genetic diseases typically have one normal allele and one mutated allele for the disorder, which means they possess recessive genes. They do not express the disease phenotype because the normal allele is sufficient to mask the effects of the recessive allele. However, they can pass the mutated allele to their offspring, potentially leading to the expression of the disease if the child inherits another mutated allele from the other parent.
Two parents who were phenotypically normal had to children The oldest was also phenotypically normal but the younger child had cystic fibrosis what is happening in the cross?
Cystic fibrosis is an autosomal recessive genetic disorder, meaning that a child must inherit two copies of the mutated gene (one from each parent) to express the condition. In this scenario, both parents are likely carriers of the cystic fibrosis allele (genotype Cc), where "C" is the normal allele and "c" is the mutated allele. The older child is phenotypically normal, which could mean they are either homozygous dominant (CC) or a carrier (Cc), while the younger child inherited two copies of the mutated allele (cc) from both parents, resulting in cystic fibrosis. This cross illustrates Mendelian inheritance patterns, where two carrier parents can have a child with a recessive condition.
