Answer the following questions based on the above (rainy season) data. 1. What was the general trend (comparing Generation 1 to Generation 4) of the brown allele frequency over the four generations? Did the brown allele frequency increase or decrease? Write the actual numbers for each generation here in support of your answer. 2. What was the general trend (comparing Generation 1 to Generation 4) in the green allele frequency over the four generations? Did the green allele frequency increase or decrease? Write the actual numbers for each generation here in support of your answer.

The next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individuals Aa = 54 individuals aa = 128 individuals What is the expected frequency of the AA genotype if the population is in Hardy-Weinberg equilibrium( you may round your answer to 3 decimal places) What is the expected frequency of the aa genotype of the population is in Hardy-Weinberg equilibrium? ( You may round your answer to 3 decimal places)

What is the chi-square value of the pumpkin population? round up and use four decimal points After doing some crosses and genotyping some individuals, you determined that the number of individuals homozygous dominant for the largest pumpkin allele is 98, 80 are heterozygous for medium size, and 20 are homozygous recessive for small size.

In carnations, the red pigment (RR) is incompletely dominant to white (rr). The heterozygote (Rr) is pink. In a randomly mating field of carnations, 42 plants were red, 178 plants were pink, and 180 plants were white (total =400). What is the best estimate of the allele ferequency, for the red allele in this population?

Can you please make a conclusion for this? Thank you so much!   Suppose you counted 79 R_ and 33 rr. The total number of individuals you counted, N, is 112. You expect 3/4 to be R_ (84) and 1/4 to be rr (28). Are your results close enough to these ratios for you to accept the null hypothesis—that there is no real difference?   Individual'sPhenotype Observed number Observed Ratio Expected Ratio Expected Number (Observed no. – Expected no.)^2 / Expected number R_ 79 2.8 3 84 (79-84) ^2 = 25/84 = 0.297 rr 33 1.18 1 28 (33-28) ^2 = 25/28 = 0.893  TOTAL: 112       Chi Square Value =  1.19 Degrees of freedom = 1

You were tasked to conduct a field observation of a population with two distinct forms, which you temporarily named "Big A" and "small b." These two forms mate and produce offspring together. For each form, you tabulated the frequency distribution of lifetime offspring production, as shown in the figure. The filled bars represent the lifetime progeny frequency distribution for "Big A" and the open bars "small b." Which of the following statements is correct? 0 1 2 4 20 # of lifetime progeny "small b" is likely having a male sexual role. "Big A" is likely to have a female sexual role. "small b" is likely to be choosy. Both are likely to be competitive. frequency

Summarise the data on morph frequencies, allele frequencies and index of polymorphism for the three populations in a table. b. Summarise in a table the estimates of genetic differentiation (FsT) between the populations for both shell colour and banding alleles. Note that you do not need to aenerate bar charts for each of the populations. c. With reference to all the information given in Table 1 and summarised in your tables in (a) and (b), explain how each of these samples differs from the others, and which of the samples are most genetically similar to each other. It should be clear from your answer on what evidence your conclusions are based and your answer should be no more than…

What is the frequency of the T allele in the current gene pool?   Question 3 options:   0.68   0.435   0.52   0.84

The next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individuals Aa = 54 individuals aa = 128 individuals What is the frequency of the A allele? (You may round your answer to 2 decimal places) What is the expected number of individuals with the AA genotype if the population is in Hardy Weinberg equilibrium? (You may round your answer to the nearest whole number) What is the expected number of individuals with the Aa genotype if the population is in Hardy-Weinberg equilibrium? (you may round your answer to the nearest whole number)

A species of butterfly shows variation in the length of the antennae. You measure antennae in a butterfly population and find the mean to be 15 mm. You calculate a heritability of antennae length to be 1 (h2 = 1). %3D That summer, there is a severe drought. Many of the butterflies die and only a few survive to reproduce. The surviving butterflies have a mean antennae length of 17 mm. a) What is the predicted mean limb-length of the offspring of the surviving butterflies? [ Select ] b) What type of selection was acting on antennae length in these butterflies? [ Select ] c) Five years later, you go back and measure antennae length in this butterfly population again. Every butterfly in the population has antennae measuring 16 mm. What is the heritability of antennae length in this population now? [Select ]
