The woman could be AA or AO and the man could be BB or BO. The children would all be AB.
Assuming the dystonia is hereditary and is a recessive gene which will be called "d" for simplicity, that means the man must be "dd" and the woman is "Dd". This is the only way they could have a child who is "dd" like the father, but not the mother.
A person with AAbb genotype would have black hair. The genotype A means the person has black hair, while bb means the person has blue eyes.
Type B blood. Children of a parent with type A and a parent with type AB blood can only have type A, type B, or type AB blood types, as type A and type B are dominant over type O.
Their children can have blood groups A or O.
Marriage has nothing do to with genotypes. Marriage, a blow to the head, oranges, and playing golf are all the same in that they don't affect genotypes in any way.Now...perhaps you meant to ask about the offspring of a man and a woman with such genotypes. Traditionally marriage precedes the birth of a child, but not always, so call it what it is: sex. So the question is if a man (genotype AS) has sex with a woman (genotype AS), will the baby be at risk for sickle cell anemia. There is a 25% chance that the child will have the disease (genotype SS).Again, to drive the point home, the proper wording of this question should not include "can" even if we get rid of the marriage nonsense. Ability here is not an issue. We also can't answer if they should have a baby, because that is entirely their decision even if they know the risks.
Do a punnet square.I am really bad at them, otherwise I would be more helpful. Got a C in biology.
If all the children are AB, then one parent is AA and the other is BB.
there is a 50% chance that the child will be colorblind. If it is a boy, it will be colorblind, but if it is a girl, it will only be a carrier. Mother's chromosome is XrXr and Father's Chromosome is XRY, which means the children's genotypes will be XRXr if girl and XrY if a boy.
What you mean by this question?
None what so ever.

There is a 25% chance that their first child will have type O blood if both parents are heterozygous for blood type A and B. This is because the child could inherit an O gene from each parent, resulting in blood type O.
Type B blood. Children of a parent with type A and a parent with type AB blood can only have type A, type B, or type AB blood types, as type A and type B are dominant over type O.
Yes.
Firstly, if the condition is recessive, both the man and the child with the condition must have the genotype tt. The mother must have the genotype Tt. This is because if she had TT, all of the children would be Tt and not have the condition. If she were tt, she would have the condition as well. Therefore if the father has tt and the mother has Tt, the other 3 children who do not have the condition must all have the genotype Tt. So: Mother - Tt Father - tt Affected child - tt Other children - Tt
If you want to have children you will have to educate yourself about the negative blood type. If you become pregnant with a child that has positive blood, you may encounter complications if not treated. There is a simple shot they will give you while pregnant and after giving birth that will prevent any problems.
