Title: Why are there so many phenotypes in polygenic inheritance?
Post by: ilovehkhk on Mar 13, 2013
Why are there so many phenotypes in polygenic inheritance?

A. There are many alleles for each gene
B. Many genes for the same trait interact to produce a continuous range of phenotypes
C. All of the alleles are dominant
D. All of the alleles are recessive

I am thinking that the second choice is the correct answer. Any help would be great.
