Card 15 / 33:
The gene for flower position in pea plants exists as axial or terminal alleles. Given that axial is dominant to terminal, list all of the possible F 1 and F 2 genotypes and phenotypes from a cross involving parents that are homozygous for each trait. Express genotypes with conventional genetic abbreviations.
Because axial is dominant, the gene would be designated as A . F 1 would be all heterozygous Aa with axial phenotype. F 2 would have possible genotypes of AA , Aa , and aa ; these would correspond to axial, axial, and terminal phenotypes, respectively.
