Green (G) is dominant to yellow (g) in a population of Yahara minnows at Hardy-Weinberg Equilibrium. 49% of the Yahara minnows are yellow. Due to more frequent algal blooms, the fitness of the yellow Yahara minnows has declined to only 25% of the fitness of the green Yahara minnows. What is the frequency of the yellow (g) allele after one complete generation of selection with random mating? If applicable, report exactly 4 significant digits.

In your biology lab you are growing brine shrimp under 3 different conditions (cultures A, B, and C). Every day you pull out a sample and count the brine shrimp and, from that, estimate the number of brine shrimp in your full culture. You graph your data as shown below. Select which culture(s)’ growth is/are described by each of the following statements: Has the largest “r” value [ans1] Shows the effects of intraspecific competition [ans2] Might have a carrying capacity of 20,000 [ans3] Has the smallest “r” value [ans4] Growth described by the equation dN/dt= rN((K-N)/K) [ans5]

Pick either “likely true/true” or “not necessarily true/false” regarding each statement below about semelparity Reproduces multiple times in its lifetime [ans1] Will outcompete an iteroparous organism [ans2] This reproductive strategy is favored in an unstable environment where during some reproductive seasons there is a low chance of successful reproduction [ans4]

Mutations in a particular developmental gene occur at a rate of 10-4 in a population of Kegonsa dragonflies. The mutant alleles are fully recessive and lead to a crumpled wing phenotype that is only 10% as fit as wild type. What will be the equilibrium frequency of mutant alleles? If applicable, report exactly 3 significant digits.
