Two genes are in strong linkage disequilibrium (LD) in a population, with a value of D =
0.16.
a. If the two genes are on different chromosomes and the population undergoes
random mating for two generations, what will the new values of D be after those
two generations? [Show calculations, but no written explanation necessary].
b.Would your answer to part (a) increase, decrease, or stay the same if the genes were on the same chromosome? Briefly explain why
Homework Answers
After n generations of random mating, the measure of association Dn is calculated as follows:
a.
b.
If the two genes are on the same chromosome, the genes are said to be linked. The r value is less than 0.5 in this case, and D decreases more slowly. That means, the value of D increases if the two genes are on the same chromosome.

Create two different populations that are each individually in linkage disequilibrium, but when combined are in linkage equilibrium. Use two loci, each with two alleles. None of the populations are allowed to have any of the chromosome frequencies equal to zero. Demonstrate that each population satisfies these requirements (i.e., show that the two original populations are in LD and the combined population is in LE).

Multiple choice: The measured distance between genes D and E in a two-point testcross is 50 map units. Where are genes D and E in relation to each other? D and E are on different homologous chromosomes. D and E are on the same chromosome, at least 50 map units apart. D and E are on the same chromosome, exactly 50 map units apart. D and E are on the same chromosome, less than 50 map units apart. A) 1...

1.) Explain why linkage measurements are more accurate for two genes that are close together than two genes that are farther apart. 2.) A female poodle with green eyes (recessive) and yellow spots on her tongue (recessive) was bred with a male poodle who was the wild-type phenotype but hybrid genotype for those same two traits. In a series of litters, this breeding pair gave birth to the following 85 puppies: 39 Normal eyes, normal tongue 36 Green eyes, yellow-spot...

C++. Need some help getting started. We will also have the following two functions: 1. A mutate function that randomly modifies a chromosome. 2. A crossover function that takes two chromosomes and splits each one at the same spot, then combines them together. Our genetic algorithm works by iterating over generations of chromosomes via the following process: 1. Generate random population. 2. Until we get an answer that is good enough, do the next steps in a loop: (a) Do...

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?

On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...
