I need help answering these questions. The table census table is provided to answer question 8. Consider the following species of squirrel in answering the questions on this test. The Lesser FluffySquirrel lives on islands in the Pacific. You study three islands (A, B, and C) along with a very largemainland population. The following table shows census information for several years of the study:Island AIsland BIsland C198047121Population censuses (numbers of squirrels)200018117199012100501201060101202062130546498512536Mainland(mainland was not censused, treat as very large)The Lesser Fluffy Squirrel has two genes of interest. The Y locus has two alleles (Y = yellow, y =black; and Y> y, Y is dominant to y).. The F locus controls fur length such:F-F² = long furF-F$ = medium fur F$F$ = short fur%3D 7.

5) A mutant red coat color allele (Yr) arises in island B and is present in the adult population in a heterozygous individual in the population of 117 adults of year 2000. Yr is recessive to the other alleles at the Y locus. What is the probability (p) that, purely by the action of genetic drift, the allele will rise to fixation (reaching a frequency of 1.0) at some time in the future? (A) 0.0 < p < 0.2 (B) 0.2 < p < 0.4 (C) 0.4 < p < 0.6 (D) 0.6 < p < 0.8 (E) 0.8 < p < 1.05 6) For the same genetic scenario, what if the single red allele arose in the island A and was present by 1990 in a heterozygous individual, one of a population 12 individuals. Would this red mutant allele have a better or worse chance of rising to fixation relative to the island B population of problem 5? (A) red allele more likely to reach fixation in A island beginning in 1990 compared to B island beginning in…

1. A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles? What are the expected numbers of the three genotypes, assuming random

9) This chart shows the beak length of a population of finches in the Galapagos. The island was faced with a five year drought that made it difficult for birds to get water. If natural selection occurs, how would you predict the bird beak lengths to change? A) Only those with shorter beaks would survive. B) The population would not really change much. C) Only those with the longest beaks would survive. D) Those with medium-long beaks would increase most. Not Graded
An Eastern European immigrant carrying the allele for Tay-Sachs disease settled in a small village on the St. Lawrence River. Many generations later, the frequency of the allele in that village is statistically higher than it is in the immigrants homeland. The high frequency of the allele in the village probably provides an example of: a. natural selection. b. the concept of relative fitness. c. the HardyWeinberg genetic equilibrium. d. phenotypic variation. e. the founder effect.
If a populations allele and genotype frequencies remain constant from generation to generation, (a) the population is undergoing evolutionary change (b) the population is said to be at genetic equilibrium (c) microevolution has taken place (d) directional selection is occurring, but only for a few generations (e) genetic drift is a significant evolutionary force
