If all offspring of a cross have the genotype Aa, the parents of the cross would most likely be
|
|
AA x aa
|
|
|
Aa x Aa
|
|
|
Aa x aa
|
|
|
AA x Aa

Explanation:
Detailed explanation-1: -So, the correct answer is ‘All Aa’.
Detailed explanation-2: -Final Answer: When Aa individual is crossed with the homozygous dominant AA, the phenotypic ratio of the offspring will be progeny will be all dominant type.
Detailed explanation-3: -Two people are said to have compatible genotypes when there is no possibility of them birthing a child with sickle cell disease. Genotype AA is the universally compatible genotype that is, regardless of who they partner up with, there is no possibility of them birthing a child with sickle cell disease.
Detailed explanation-4: -No, if both parents are AA, the offspring will all be AA. For AS offspring, at least one parent must be AS.
