What is the probability of a man who has BB genotype and his wife who has BO genotype to have a child who is AB?
No probability. Neither parent has an "A" for the child to inherit to make an "AB".
What is the percent probability that one child of a mother with the genotype AAA and a father with the genotype AAA will have the genotype AAA?
50% AA and 50% Aa
Can a child have sickel cell if the father does not?
yes, as it's genetic
What is the probability of am man and woman giving birth to a child who to is sickle cell like both of them?
If both parents are carriers of the sickle cell trait (genotype AS), there is a 25% chance that their child will inherit the sickle cell disease (genotype SS). Each parent has one normal hemoglobin allele (A) and one sickle cell allele (S), which means the possible combinations for their child are AA, AS, and SS. Therefore, the probability of the child being affected by sickle cell disease is 25%. If both parents have sickle cell disease (genotype SS), then all children will also be affected (100%).
Sue has O blood type and Bill has A blood type. Their child named Anna has A type blood. Anna marries Bill who has AB type. What is the probability that Anna and Bill's child will have A type blood?
To determine the probability that Anna and Bill's child will have A type blood, we first consider their genotypes. Anna, with A type blood, could have either AA or AO genotype, while Bill, with AB type blood, has genotype AB. If Anna is AA, all their children will be A type. If she is AO, there’s a 50% chance of A type blood (AO) and a 50% chance of O type blood (OO). Therefore, the probability that their child will have A type blood ranges from 50% to 100%, depending on Anna's genotype.
A woman is homozygous for A-negative blood type. A man has AB-negative blood type. What is the probability that the couples child will be type B-negative?
The genotype of the man is A negative/O negative inheriting the A neg from his mother and O negative from his father. [Father's genotype is B positive/O negative. Mother's genotype is B positive/A negative.]
What is the genotype of a woman with A blood and a man with b blood and a child with o blood?
The woman would have genotype AO (IAIA) for blood type A, the man would have genotype BO (IBIB) for blood type B, and their child with blood type O would have genotype OO (ii). The child inherited one O allele from each parent.
Can a child's genotype be different from that of both parents?
A genotype is decided from two alleles. One of these alleles comes from the father, and one comes from the mother. Thus it should be clear that the genotype can be different from both parents. For instance, suppose the father has genotype AA, and the mother has genotype aa. In this case, the child will have genotype Aa, which neither parent has.
Can a child have O positive blood if both parents are A positive?
Yes, if both parents are AO genotype there is a 25% chance of the parents producing a type O child. Since both parents are Rh positive the probability of an Rh positive child in at least 75%.
What is the child's genotype if parents both have normal arches produce a child with flat feet?
Child's genotype would be homozygous recessive alleles (nn) and parents would both have heterozygous dominant alleles (Nn).
What is the probability of a child having cystic fibrosis if one of her parents was homozygous dominant and the other was a carrier for cystic fibrosis?
Assuming that each parent is a carrier for cystic fibrosis (has the genotype Ff), the probability that their second child will develop cystic fibrosis is one fourth. The probability doesn't change with the number of children they have. For each pregnancy, the chance that the child will have cystic fibrosis (have the genotype ff) is exactly the same.
Can parent with as and AA genotype give birth to ac genotype?
No, a parent with AS and AA genotype cannot give birth to a child with AC genotype. The parent can only pass on either the A allele or the S allele to their child, resulting in genotypes of either AA or AS.
