Why Is Mating in Humans Always Effectively Random Even If

question 7

Multiple Choice

Why is mating in humans always effectively random even if individuals were to intentionally pick mates based on the absence of important genetic diseases?

• A) Even if all the genetic loci are used in making a mate choice, the next generation randomizes the genes anyway.
• B) In humans, there is no linkage, even between genes located near each other on the same chromosome.
• C) The mating is still random across almost every one of the more than 22,000 loci across the human genome.
• D) Humans lack genetic diversity; therefore, almost all human genes have a single allele.
