Many species of birds choose their mates based on how brightly colored they are. If feather color is heritable, how would this violate the assumptions required for a population to be in Hardy-Weinberg equillibrium? HW equilibrium would cause mutations in such a species. OA. This is a founder effect B. This is a bottleneck effect On Mating is non-random. Alleles for brightly colored phenotypes might become more common in the species and allele frequency would change.

A. The Hardy-Weinberg Equilibrium is important because it serves as a null hypothesis in studies that evaluate evolution of species. it explains how evolution works. it predicts how allele and genotype frequencies will change over time. it clarifies how traits are passed from parent to offspring. B. Hardy-Weinberg Equilibrium occurs frequently in natural populations. predicts changes in allele and genotype frequencies. is inhibited by random mating. assumes large population sizes.
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 inbreeding
There is an outbred population of mice living in a farmer’s field. Mutations occur at a genecalled nurseryrhyme that cause a totally recessive form of blindness (h=0). These blind micedo not survive to reproduce because the farmer’s wife cuts off their tail (and other bits) witha carving knife. Surveying the field for baby mice you find that 3/10,000 mice are blind.A. Assuming that the population mates at random, what is the mutation rate of blindnesscausing alleles?B. Following more careful study you now find that there is actually a 20% reduction in theviability of heterozygotes for these mutations. What would you now estimate as themutation rate for this gene?

A population of self-pollinating pea plants has two genes; T (tall, dominant) and t (short, recessive). Suppose we have an isolated population in which 50% of the genes in the gene pool are dominant T, and the other 50% are recessive t. What percent of the population has each genotype?
Suppose a species of bird called the red‑crested warbler has a plumage length that is controlled by a single gene. The P l m allele produces long plumage and is dominant over the p l m short plumage allele. One population exists in North America (NA) and a separate population exists in South America (SA). The trait is in Hardy–Weinberg equilibrium in each population. An island nature preserve brings in 102 NA warblers and 352 SA warblers. Out of the 102 NA birds, 55 have long plumage. Out of the 352 SA warblers, 75 have long plumage. After the birds from the combined populations mate randomly, the island population produces 1000 offspring. Calculate the number of these offspring that are expected to have long plumage. Round the number to two significant figures. number of offspring with long plumage.
