If Genes are Linked and an F₁ is Testcrossed

Question

If genes are linked and an F1is testcrossed,
A)the genes cannot separate.
B)they can produce only one phenotype.
C)they only produce homozygotes.
D)they produce more recombinant phenotypes than parental phenotypes.
E)they produce more parental phenotypes than recombinant phenotypes.

Accepted Answer

When genes are linked, they tend to be inherited together and produce more parental phenotypes than recombinant phenotypes. Therefore, the testcross of an F₁ individual will likely result in more parental phenotypes than recombinant phenotypes.
