Question

which of the following scenarios would prevent a population from being in hardy-weinberg equilibrium?
a) the population is evolving, and natural selection is favoring one allele over another.
b) the population will fall out of hardy-weinberg equilibrium if natural resources such as food are limited.
c) the population mates at specific times of the year, causing the population to fall out of equilibrium at that time of year.
d) the population is stable, but younger generations of the population have a different allele frequency.
question 2 (5 points)
listen
embryology provides evidence for evolution because
a) during their development, embryos experience genetic mutations, some of which allow the embryo a better chance of survival.
b) during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.
c) studying organisms during their early development provides clues as to how the adult functions.

Explanation:

Question 1

The Hardy - Weinberg equilibrium has conditions including no natural selection, no mutation, large population size, random mating, and no gene flow. If natural selection favors one allele over another (as in option A), the allele frequencies will change, preventing the population from being in Hardy - Weinberg equilibrium. Option B: Limited natural resources don't directly violate Hardy - Weinberg conditions. Option C: Mating at specific times doesn't necessarily mean non - random mating in a way that violates Hardy - Weinberg (random mating is about mating not being based on genotype, not time of year). Option D: If the population is stable, allele frequencies should not change, so this statement is contradictory and not a valid reason for being out of equilibrium.

Question 2

Embryological evidence for evolution comes from the fact that many different species have similar embryonic development. For example, vertebrate embryos (like humans, fish, birds) have similar structures in early development, which implies a common ancestor. Option A: Embryonic development mutations are not the main embryological evidence for evolution. Option C: Studying embryo development for adult function is not related to evolution evidence.

Answer:

A) The population is evolving, and natural selection is favoring one allele over another.
