You are a biologist interested in the variation in the body size of Florida sea turtles. You krnow that body size is determined by a single locus. with two alleles, with large body size (A) dominant over small bOdy size (a) survey the body size of 100 turtles and observed the following phenotype frequencies: Large bodied turtles (AM and Aa) - 84 Small bodied turtles (aa) - 16 If the population is in HWE, how many turtles of each genotype would you expect? O AA - 84, Aa - 0, and aa = 16 O AA - 36, Aa- 48, and aa = 16 O AA - 42, Aa - 42, and aa - 16 O AA - 24, Aa - 60, and aa - 16 O AA - 16, Aa - 68, and aa 16

You observe some bark beetles with different feeding behaviors. You find that the behavioral phenotypes you observed are closely associated with the following genotypes.   genotype phenotype number observed BB feeds under bark 60 Bb feeds on top of bark 24 bb feeds on leaves 16     a) What are the allele frequencies and the expected number (out of 100 beetles) of genotypes? b) Calculate the Chi-Squared value (c2). Then look up the p-value only using this Chi-squared calculator: https://www.mathsisfun.com/data//chi-square-calculator.html    Clear all the values in the box at upper right, enter the Chi Square value that you obtain FROM YOUR CALCULATIONS in the Chi-Square box, and enter 1 for the degrees of freedom. Is the population in H-W equilibrium?   c) If you answered “No” to b): Provide at least three biologically valid reasons why the observed beetle population may not be in equilibrium.   If you answered “Yes” to b): Why do you think this…

A population of turtles is found where dark shells are completely recessive to light shells (denoted by the alleles a and A). In your survey you captured both dark shelled turtles (452) and light shelled turtles (478). 1. 0.717 2. 0.283 What is the genotypic frequency of light shelled individuals in the 3 3. 0.303 population? 4. 0.486 What is the frequency of the a allele? 5. 0.514 6. 0.697

You decide to examine call duration in Canadian toads at Big Lake near Edmonton. Call duration in the toads is determined by a single autosomal locus "noisy", at which there are two alleles (N & n). You observe three distinct call patterns in the toad population: Long duration, intermediate duration and short duration calls. Based on research from Dr. Phoney Balloni longer calling is dominant to short duration. On one evening at Big Lake you and your socially distanced assistants record the phenotypes of the toads in the table below. Phenotype No. of individuals Long 123 Intermediate 226 Short 101 Determine whether the population is in Hardy-Weinberg equilibrium. a) What are the frequencies of N and n?. b) What are the expected frequencies for each phenotype? c) Is the population is in HW equilibrium?

Color in a species of minnows is determined by a single locus with two alleles: D and d. DD individuals are dark, Dd are intermediate, and dd are pale. In a population that is in Hardy-Weinberg equilibrium, we count 8 pale minnows out of 57. How many minnows do you expect to be dark? Round your answer to the closest integer value. Your Answer: Answer

A different locus codes for drought tolerance in desert tortoises. On average during a drought, genotype AA produces 7 offspring, genotype AB produces 8 offspring, and genotype BB produces 3 offspring. The genotype frequencies in 2019 are 10% AA, 10% AB, and 80% BB. What is the expected equilibrium allele frequency p* after a large number of generations go by during the drought? Assume the tortoise population is also very large.

You sample a population of 189 mule deer for ear length alleles and find that 32% have AA, 42% have AB, and 26% have BB. If the HWE expected frequencies are AA=28%, AB=50%, and BB=22%, is this locus in HWE?

The color distribution for a specific population of snakes is 160 blue, 50 turquoise, and 40 green. The allele for the color blue is represented by B", whereas the allele for the color green is represented by BC. Both alleles demonstrate incomplete dominance. What are the genotype frequencies in the population? Calculate to at least two decimal places. BBBB : BBBG : BGBG. What is the allele frequency of B5 in this population? Calculate to at least two decimal places. allele frequency of BB:

Butterflies show 3 phenotypes due to incomplete dominance at the D locus with alleles DY and DB giving green phenotype in heterozygotes and yellow and blue in homozygotes. A population of butterflies showed 49% yellow, and 51% blue and green. If the butterflies were subject to predation by birds that could easily detect blue & yellow individuals what effect would you expect this to have on the genotype and allele frequencies over time? Indicate possible percentages.

In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss).    Question: The expected number of smooth fur hamsters (SS) in the next generation of 1000 hamsters is:   Question 3 options:   0.390   470   625   390
