Question

if pointed heads are dominant to round heads, which of the following genotypes could express a round phenotype
​

Answer 1

Answer:

D - Pp

Explanation:

I initially thought it would be A - PP, but I realized D is actually the best answer since it includes both phenotypes with the allele for round heads (P) being dominant and, therefore, expressed.

Hope this helps you figure out the answer :) Have an awesome day!
