- What is population genetics?The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met. Choose Yes or No for the conditions that must be met from the providied statement below. 1. Mutations are exponentially occuring 2. All member of the population breed 3. Everyone produces the same number of offspring 4. The population is infinitely large 5. There is no migration in or out of the population 6. No net mutations are occuring 7. Natural selection of beneficial traits is occuring 8. Natural selection is not occuring 9. All mating is completely random 10. Offspring are able to migrate out of the populationWhat is the intuitive meaning of the mean fitness of a population? How does its value change in response to natural selection?
- There are two traits in moths: light color and dark color. If a population has 60%of the moths with the light color, using Hardy-Weinberg, what can be predicted about the offspring of the population if no environmental factors are present? 40%of the offspring will be dark in color 40%of the offspring will be light in color 60%of the offspring will be dark in color 50%of the offspring will be each colorA scientist is studying a wild population of Japanese morning glories. It is easy to separate genotypes at a flower color locus by their phenotypes. Red individuals are homozygous for the R allele, yellow individuals are homozygous for the Y allele, and orange individuals are heterozygous. If the number of individuals with the following genotypes are: RR: 831 RY: 33 YY: 442 Is the population in Hardy Weinberg Equilibrium?The gel image below shows 7 alleles, let's call them 1-7 in order of size, with 1 being the largest and 7 being the smallest.

- A population consists of 7 mice. For the coat color trait, there are only two alleles: brown (B) and white (b). BB and Bb mice are brown; bb mice are white. In the population's gene pool, there are 7 white alleles (b). a) What is the frequency of the brown allele in the population? Select) b) What do you predict the frequency of the bb genotype will be in the next generation if no evolution takes place in the population? I Select | c) The mice live on dark black, volcanic rocks in the Arizona desert and two hawks are introduced into the area as part of wildlife rehabilitation program. You sample the mouse population after the hawk reintroduction and find the following numbers: 24 BB mice, 52 Bb mice, 24 bb mice. Has natural selection by the hawks caused the population to evolve significantly? I Select]background: Lizards often have bright coloration and in some species there is variation in coloration within populations. For the sake of simplicity, let’s assume that color is genetically determined by a single gene with two alleles that interact in a codominant fashion: r+r+ = red, r+r- = yellow, r-r- = white. Imagine there is a large population of these lizards where 1 in 200 lizards have the white coloration, 30 are yellow and the rest are red. A tsunami sweeps through the population! Although no lizards died, 10 random lizards were swept to a nearby island. One of these individuals is white while the rest were yellow. Over time, these individuals remain stuck on the island and form a new population. Eventually, 80% of this population has the white coloration. Assume that color does not affect fitness in either population. question: At the time of the founding of the smaller population, (when 1/10 were white, the rest yellow), what was the chance of fixation of the r- allele via…There are particular factors that cause the diversity in a gene pool to change.
