Despite the law of independent assortment, when two loci are on the same chromosome, the phenotypes of the progeny sometimes do not fit the predicted phenotypes due to
A) translocation.
B) inversions.
C) chromatid affinities.
D) linkage.
E) reciprocal chromosomal exchanges.

Question

Quizplus · Accepted Answer

When two loci are on the same chromosome (i.e. they are physically linked), they do not assort independently. This means that the alleles at these loci tend to be inherited together more often than if they were on different chromosomes. This phenomenon is known as linkage, and it can result in offspring phenotypes that do not match the predicted ratios based on Mendelian genetics.
