|
If all F1 generation is Aa, then the expected crossing between parents’ genotypes are
|
|
AA x Aa
|
|
|
AA x aa
|
|
|
Aa x Aa
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -So, we can say that the offspring obtained from the cross had Aa as their genotype which was different from the parental genotype and the phenotype of the offspring is A as it is the dominant trait. So, the answer is ‘genotypically Aa, phenotypically A’.
Detailed explanation-2: -So, the correct answer is ‘Genotypically Aa, phenotypically A’
Detailed explanation-3: -All of the F1 generation plants will have the genotype of Ss (heterozygous), and all will be spherical seeded.
