In a test cross involving linked genes, the frequency of parental phenotypes in the offspring will be:
Show answer and explanation
Correct answer: Significantly higher than the frequency of recombinant phenotypes
When genes are linked, they tend to stay together during gamete formation. Consequently, parental combinations appear more frequently in the progeny than the recombinant types created by crossing over.
