Final answer:
The term for mating without regard to genetic makeup is random mating. None of the provided options (A-D) accurately describe this type of mating, as they all involve some degree of selection based on genetic traits or system of mate choice.
Step-by-step explanation:
Mating that occurs without regard to the genetic makeup of individuals is known as random mating. The options given in the question confuse different types of mating behaviors. Assortative mating (A) is when individuals nonrandomly mate with those who are phenotypically similar to themselves, non-random mating (B) is a broad term that includes any mating system that is not random, inbreeding (C) is when closely related individuals mate with each other, and monogamous mating (D) is a system where individuals only have one mate at a time.
Since the question asks about mating without consideration of genetic makeup, the correct term is not included in the provided options. Random mating is, by definition, not influenced by any trait or genetic makeup. It should be noted that in the natural world, truly random mating is rare because of multiple factors like mate choice, physical location, and environmental variance.
