Concept explainers
I. A population called the founder generation, consisting of 2000 AA individuals, 2000 Aa individuals, and 6000 aa individuals is established on a remote island. Mating within this population occurs at random, the three genotypes are selectively neutral, and mutations occur at a negligible rate.
*help needed for sub questions d-f.
a. What are the frequencies of alleles A and a in the
founder generation?
b. Is the founder generation at Hardy-Weinberg
equilibrium?
c. What is the frequency of the A allele in the second
generation (that is, the generation subsequent to the
founder generation)?
d. What are the frequencies for the AA, Aa, and aa
genotypes in the second generation?
e. Is the second generation at Hardy-Weinberg
equilibrium?
f. What are the frequencies for the AA, Aa, and aa
genotypes in the third generation?

- please answer all parts with good explanationsarrow_forwardA different locus codes for drought tolerance in desert tortoises. On average during a drought, genotype AA produces 7 offspring, genotype AB produces 8 offspring, and genotype BB produces 3 offspring. The genotype frequencies in 2019 are 10% AA, 10% AB, and 80% BB. What is the expected equilibrium allele frequency p* after a large number of generations go by during the drought? Assume the tortoise population is also very large.arrow_forwardplease help with these two questions: 1. Which of these statements is/are NOT true about genetic drift? a. Statement 3. Genetic drift does not occur in large populations. b. Both statements 2 and 3. c. Statement 2. Genetic drift happens faster in large populations than in small ones. d. Statement 1. Genetic drift can cause the loss of an allele in a species. e. Both statements 1 and 2. 2. A genetic bottleneck in a population often results in what? a. Loss of alleles. b. None of the above. c. An increase in genetic drift. d. All of the above. e. Loss of genetic diversity.arrow_forward

Group of answer choices A. A connected series of neighboring populations that can interbreed with one another with one end population in the series that are two distantly related to interbreed and thus are separate species B. A connected series of neighboring populations that cannot interbreed with one another with at least two end populations in the series that are two distantly related to interbreed and thus are separate species C.

- A new species of snail was discovered. Your initial population genetics survey found that fA:0.48. To determine the primary mode of reproduction you survey the population again in one generation. You collect 100 individuals in the next generation. The composition of your collection is AA=38, Aa=20, aa=42. What is the primary mode of reproduction? a. random mating b. not enough information to determine c. nonrandom mating due to inbreedingarrow_forward1.
