What alleles would the offspring have if both parents are pure a or pure A?

If the parents are both AA, which results in the cross AA X AA, then the offspring will all be AA. If both parents are AA, resulting in the cross AA X AA, then all offspring will be AA. If BOTH parents are Aa, resulting in the cross Aa X Aa, then the offspring will be 25% AA, 50% Aa, and 25% AA. This is only true if the alleles are not sex-linked.


Suppose a women with normal colored skin and having an albino mother married an albino man What would be the genotype of the woman?

The albino woman has to be AA. So the man has to be either AA or Aa in order to be normal. So if they have a baby and its albino it has to contain the AA gene. a a A Aa | Aa ---------------- A Aa | Aa doesn't work.. All outcomes are normal. a a A Aa | Aa ----------------- a AA | AA these combination outcomes 50% chance of an albino baby. This means the man is Aa Heterozygous dominant.. the mother is AA homozygous recessive.. and the baby is the same as the mother. AA...


How can you get a true breeding plant?

You can obtain a true-breeding plant by repeatedly self-pollinating a plant that consistently produces offspring with the same characteristics as the parent. This ensures that the desired traits are consistently passed on without variation.


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.
