Question

17.You are a geneticist studying the population genetics of Monarch butterflies. You are particularly interested in one gene for which the species has two alleles: B and b. Upon examining the alleles present in 100 individuals, you find that the B allele is very common, with an allele frequency of .6. Therefore, you calculate that there are a total of _______ b alleles present in the population.

Group of answer choices

A) 60

B) 80

C) 100

D) 120

E) 140

18.If population 1 is in Hardy-Weinberg equilibrium such that p = 0.7, and q = 0.3, select all of the following that would result if mating began to occur with the adjacent population 2 in which p = 0.1 and q = 0.9.  Select ALL that apply.

Group of answer choices

A) Population 1 will shift out of Hardy-Weinberg equilibrium

B) Population 2 will stay in Hardy-Weinberg

C) In population 2, p will increase

D) In population 1, p will increase

E) In population 1, q will increase

21. The pangolin is a small scaled mammal found in Africa and Asia. There are eight species globally and two of them are critically endangered, the result of severe population bottlenecks caused by overharvesting by humans for meat and for their scales.

What effect would a bottleneck likely have had on the genetic diversity of the affected population?

Group of answer choices

Genetic diversity would be less than in the original population.

Genetic diversity would be greater than in the original population.

Genetic diversity would be the same as in the original population.

A gold-finch has a range of feather color variation displayed by males. The feather colors range from a dull yellow that allows them to blend into their preferred habitat to a bright yellow that is very obvious and makes them more visible to predators. The adult females are dull colored. The predation rate for bright yellow males is three times higher than for the dull colored males. Despite this, the bright yellow plumage persists in the population.

What is the MOST likely explanation for persistence of the bright yellow plumage?

Group of answer choices

A) Females prefer the bright yellow plumage and so mate with this phenotype more often.

B) The dull-yellow plumage provides a survival advantage over the bright-yellow plumage.

C) The adults with dull-yellow plumage require less energy investment to ensure their survival.

D) Bright-yellow adult males are more likely to survive than dull-yellow birds.

E) Both B & C.

26.

Which of the following is the most likely to be a K-strategist species?

Group of answer choices

A) A species that has large numbers of offspring

B) A species that provides little to no parental care

C) A species with a relatively short life span

D) A species with relatively large-sized offspring

E) Both B & D

You are using a quadrat to estimate the number of sugar maple trees in your neighborhood park. The park is 2 square miles. You divide park into 100 equally sized sections. You count the number of sugar maple trees in 10 of the 100 sections. In those 10 areas, you count a total of 500 trees.

Based on this information, you estimate the density of sugar maple trees in the park as:

Group of answer choices

A) 500 trees per square mile

B) 1,000 trees per square mile

C) 2,500 trees per square mile

D) 5,000 trees per square mile

E) 10,000 trees per square mile
