Question

In a garden pea plant, the gene for flower position results in axial or terminal. The allele for axial is dominant (represented by A), and the allele for terminal is recessive (represented by a). What is (are) the only possible genotype(s) for the plant?

Answer 1

- If the plant shows the recessive terminal flowers, the only possible genotype is aa.
- If it shows the dominant axial flowers, the genotype could be AA or Aa.
