Question

The allele for tall plants is dominant over the allele for short plants, and the allele for purple flowers is dominant over the allele for white flowers. Suppose two plants heterozygous at both loci are crossed. What ratio of the offspring would be tall with purple flowers?

Answer 1

You would get 1 Tall purple flowers (TT&AA) and 2 Tall purple flowers that are carriers of the recessive gene (Tt&Aa) and 1 short white flowers (tt&aa).
