Geneticists have discovered the existence of meiotic drive genes, which have alleles that, when present in a heterozygous state, are able to become incorporated into much more than 50 percent of the gametes.As a result, the offspring ratios are not what Mendel would have predicted.Which statement about these meiotic drive genes is true?
A) They violate the law of independent assortment.
B) They violate the law of equal segregation.
C) They alter dominance relationships.
D) They alter phenotypes.
E) They are an example of blending inheritance.

Question

Quizplus · Accepted Answer

Meiotic drive genes violate the law of equal segregation, which states that each allele for a trait must separate from each other allele during gamete formation. Instead, the allele associated with the meiotic drive gene is overrepresented in the gametes. They do not violate the law of independent assortment, alter dominance relationships, alter phenotypes, or demonstrate blending inheritance.
