If a woman has type A blood and her child has type O and the father has type B is he the father?
Yes, depending on the genotypes of the parents. It the parents are both heterozygous for their blood type, then the child could have the recessive type-O allele. Each parent has two alleles in their blood types, one from their mother, one from their father like most simple genetics. If Parent A has the genotype AO and Parent B has the genotype BO then it is possible for them to have a child with the genotype OO which means O-type. These to parents have: B O A AB AO O BO OO They would have a 25% chance of having a child with AB-type, 25% chance of having a child with B-type, 25% chance of having a child with A-type and a 25% chance of having a child with O-type.
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.
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.
If a person with blood type o mates with a person with blood type b what are the possible blood types of their children?
The child will most likely be type B (genotype BO), however if the B parent is type BO, the child may be type O.
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.
What are the possible effects of 'AS' married to 'AS' and why?
There are three outcomes if a person with an AS genotype marries a person with another AS genotype. The offspring has a 50 percent chance of inheriting the AS genotype, and a 25% chance of having a child with an AA or SS genotype. Most couples who share the AS genotype choose not to procreate.
Let T mean tall and t mean short If Claras mother is Tt and her father is Tt what is?
Assuming T is dominant and t is recessive, and neither are sex-linked, Clara's mother and father are both tall. They have a 1:4 chance of have having a tall child with the genotype TT, a 1:2 chance of having a tall child with the genotype Tt, and a 1:4 chance of having a short child with the genotype tt. If neither T or t is dominant or recessive, both parents should be of medium height, with a 1:4 chance of having a tall child, a 1:2 change of having a medium height child, and a 1:4 chance of having a short child.
What type of blood a kid would have when the father has AB type and the mother A type?
If the father has AB blood, we know his genotype is AB. But if the mother has type A blood, she can either have AO or AA. If you cross AB x AO in a Punnett Square, the child would have a 50% chance of having type A blood, 25% chance of having AB and 25% chance of having type B. If you cross AB x AA, the child would have a 50% chance of having type A and a 50% chance of having type AB.
What are the chances of a woman with blood type b and a man with blood type ab having a child with type 0?
There is no chance that this baby would have the blood type O. In order for someone to have the blood type O, the genotype must be IoIo. That means that each parent would have to have an O allele in their genotype. In this case only the mother has the possibility of having an O allele. Genotypes of blood type A: IbIb, IbIo Genotype of blood type AB: IaIb Genotype of blood type O: IoIo here is a punit square to show you heterozygous mommy heterozygous daddy IbIo IaIb Ib Io Ib IbIb IbIo Ia IaIb IbIo This child would have 75% chance of having the blood type B and 25% chance of being type AB

If Parent A has the genotype AO and Parent B has the genotype BO then it is possible for them to have a child with the genotype OO which means O-type. These to parents have: B O A AB AO O BO OO They would have a 25% chance of having a child with AB-type, 25% chance of having a child with B-type, 25% chance of having a child with A-type and a 25% chance of having a child with O-type.
Can your timing of having a baby girl be disturbed if your cycle shifted by a day short?
The time at which you conceive to have a child has no bearing on the gender that your child will be: the gender of your child is dependent upon the sperm that gets to the egg first. Unless your sexual partner is not genotype XY as a male, the chance of having a female or male child is 50-50, regardless of when you become pregnant.
Having freckles is dominant (F) and not having freckles is recessive (f). A mother has Ff and a father has ff. If they have a child which genotype will make their child not have freckles?
ff (apex)

Having freckles is dominant (F), and not having freckles is recessive (f). A mother has Ff and a father has ff. If they have a child, which genotype will make their child not have freckles?
ff (apex)
A man heterozygous for blood type A marries a women heterozygous for blood type B the chance that their first child will have type O blood is?
To determine the chance that their first child will have type O blood, we can use a Punnett square. The man, being heterozygous for blood type A (genotype AO), can pass on either the A or O allele, while the woman, being heterozygous for blood type B (genotype BO), can pass on either the B or O allele. The possible combinations for their child are AO, BO, AB, and OO. Therefore, there is a 25% chance that their first child will have type O blood (genotype OO).
What would a genetic counselor tell parents who had cystic fibrosis or were carries of the cystic fibrosis about the chances of their children having cystic fibrosis?
If both parents are carriers then the child has a 25% chance of having cystic fibrosis. If one parent has CF and the other the other was just a carrier then the child has a 50% chance of having CF. If one parent has CF and the other has two normal genes then there is no chance of the child having CF. If one parent is a carrier and the other has two normal genes then there is no chance of the child having CF. If both parents have CF then there is a 100% chance that the child will also have CF.
