Question

A square shape (S) is dominant to round (s). What genotype(s) could the offspring have to have a round shape?

Answer 1

They would need to be Homozygous Recessive (ss)

Explanation: If an allele has even one dominate trait it will have the dominate trait for example Ss this would be a square head because of the dominate allele

But to have a recessive trait you need two of the recessive trait for example ss would be round

But you can have something called a homozygous dominate witch is two of the dominate trait (SS) when this happens you get the dominate trait in this case it would be square shape
