Consider the following species of squirrel in answering the questions on this test. The Lesser Fluffy Squirrel lives on islands in the Pacific. You study three islands (A, B, and C) along with a very large mainland population. The following table shows census information for several years of the study: Population censuses (numbers of squirrels) 2000 1980 1990 2010 2020 Island A 47 12 18 60 62 Island B 121 100 117 101 130 Island C 546 501 498 512 536 Mainland (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-F = long fur F-F$ = medium fur F°F$ = short fur 1. Consider island C in 1980 with 546 adults. If the frequency of the black allele (f (y)) is 0.12, assume Hardy-Weinberg conditions and estimate the frequency of heterozygotes in this island population. (A) 0.0

Question

I need help answering these questions. I'm not sure which formulas to use to solve. 

Consider the following species of squirrel in answering the questions on this test. The Lesser Fluffy Squirrel lives on islands in the Pacific. You study three islands (A, B, and C) along with a very large mainland population. The following table shows census information for several years of the study: Population censuses (numbers of squirrels) 2000 1980 1990 2010 2020 Island A 47 12 18 60 62 Island B 121 100 117 101 130 Island C 546 501 498 512 536 Mainland (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-F = long fur F-F$ = medium fur F°F$ = short fur 1. Consider island C in 1980 with 546 adults. If the frequency of the black allele (f (y)) is 0.12, assume Hardy-Weinberg conditions and estimate the frequency of heterozygotes in this island population. (A) 0.0 <f(¥y)< 0.2 (D) 0.6 <f(Yy) < 0.8 (B) 0.2 < f(Iy)<0.4 (E) 0.8 <f(Yy) < 1.0 (C) 0.4 < f(Iy)<0.6 2. Consider island C in 1980 with the following phenotypic frequencies for the F locus: f (long) = 315 Conduct a Chi-square analysis of these data and determine if the population is in Hardy-Weinberg equilibrium at the F locus. The results of your Chi-square assessment indicate that you should: (A) reject Ho that the population is in HW equilibrium (B) fail to reject Ho that the population is in HW equilibrium (C) accept Ho that the population is in HW equilibrium f (medium) = 200 f (short) = 36

Consider island C in 1980 with 546 individuals. Assume no migration in the 80's and that the 1990 census of 501 individuals represents mortality alone. Here are some survivorship numbers with regards to the Y locus: Census year 1980 Total 1990 546 501 496 Yellow 524 Black 22 5 3. Give the relative fitness (w) of the black phenotype across this interval. (B) 0.2 < Wy< 0.4 (E) 0.8 < wyy< 1.0 (A) 0.0 <wiy < 0.2 (D) 0.6 < wy< 0.8 (C) 0.4 < wyy <0.6 4. Which phenotype is more fit? (A) yellow (B) black (C) neither
