Question

As populations decrease in size, all of the following are more likely, except: Risk of inbreeding decreases Heterozygosity decreases Rare traits may disappear Deleterious alleles may be more likely to be expressed Question 4 1 pts In exponential growth, the growth curve is represented by an S-shaped curve. numerical increase in the population remains constant for each generation. population size is usually above the environmental carrying capacity. O population increases by some constant proportion of its current size.

Answer 1

As populations decrease in size, rare traits may disappear. Risk of inbreeding decreases, heterozygosity decreases, and deleterious alleles may be more likely to be expressed.

Step-by-step explanation:

As populations decrease in size, rare traits may disappear is more likely to happen while the other options are not. When a population decreases in size, there is a higher chance for rare traits to be lost because the number of individuals carrying those traits decreases. The risk of inbreeding decreases because there are fewer individuals available for mating and therefore a lower likelihood of mating with close relatives. However, heterozygosity decreases since there is reduced genetic diversity in a smaller population. Additionally, deleterious alleles may be more likely to be expressed since there is less genetic variation to mask the effects of harmful alleles.
