I'm studying for midterms, and an old test question asks this:
Multiple crosses involving genes known to occur on the same chromosome produce frequencies of phenotypes that suggest there is a high rate of crossover between these two genes. Which of the following is the most likely explanation for the phenotypic frequencies observed due to crossing over?
a) The two genes are far apart from one another.
b) The two genes are both recessive.
c) The two genes have incomplete dominance.
d) The two genes are both located far from the centromere.
e) The two genes are on the same chromatid.
My biology sense tingles when I read E. I know the answer isn't D, B, or C. A doesn't make sense, because the further apart two genes are, the more likely they are likely to have cross over between them... right?
