Consider two genes with different expected mutation rates due to size. Gene 1 has a mutation rate of 1 x 10-6 in the population, while gene 2 has a mutation rate of 3 x 10-6 in the population. Assume that the probability for an individual to have two mutations in one gene is 0. Also, the number of bases, n, in a gene is large.

1. State the probability that there are more than two people with mutations total between the two genes in your sample.

2. Consider the case that gene 2 controls the potential for mutation of gene 1. If gene 2 is mutated, gene 1 has a probability of 50% of being mutated, while if gene 2 is not mutated, gene 1 has a probability of 10% of being mutated. What is the probability that gene 1 is mutated in an individual.

1. Consider two genes that are independent, the A gene and the B gene. Each gene has two alleles (A gene: A1 and A2, B gene: B1 and B2). The frequency of A1 allele at the A gene is 0.37 and the frequency of the B2 allele at the B gene is 0.73. What is the probability of an individual in a randomly mating population of having A1A2B1B2 as their genotype? 2. In a population of bacterial cells you know...

Two different genes encode enzymes that perform different biochemical functions. 1.Singly, mutations in these two different genes cause two different phenotypes. When combined, a double mutant individual (carrying mutations in both genes) has a new phenotype! These genes are described as: Group of answer choices a.Duplicate genes b.Pleiotropic genes c.Additive genes d.Lethal genes 2. he term for a mutation that is loss-of-function, and results in zero gene activity is: Group of answer choices a.Hypermorphic mutation b.Hypomorphic mutation c.Null mutation d.Neomorphic...

Section C – Mutation of SARS-CoV-2 Over Time All viruses accumulate mutations over time, and different classes of viruses have different mutation rates based on the fidelity with which their genomes are replicated. Viral mutations can affect the accuracy of tests, the efficacy of vac- cines, and virulence (the ability to spread, the seriousness of illness, etc.). In this section you will compare a number of sequenced genomes from clinical samples during the first several months of the COVID-19 outbreak...

Consider a population of individuals each of whom possesses two genes which can be either type A or type a. Suppose that in outward appearance type A is dominant and type a is recessive. (That is, an individual will have only the outward characteristics of the recessive gene if it is aa.) Suppose that the population has stabilized, and the percentages of individuals having respective gene pairs AA, aa, and Aa are p,q, and r. Call an individual dominant or...

1. Consider two genes in the rabbit. Allele C is dominant and produces rabbits with full color. The recessive allele c produces albino rabbits. The second gene controls the color of the fat. Allele Y produces rabbits with white fat and the recessive allele y produces yellow fat. A series of 2-point test crosses with a dihybrid rabbit produced the following progeny: albino with white fat, 22; full color with white fat, 3; albino with yellow fat, 4; full color...

3) Imagine a mutation occurs which introduces an intron into the coding sequence of a gene. Relative to the intron-free wild type allele, the selection coefficient against this mutant allele with an intron will be approximately s = -2.5 x 10-8.   Now consider what happens if this mutation occurs in the yeast Saccharomyces cerevisiae which has an estimated effective population size of Ne = 1 x 107 versus the mutation occurring in a different species of yeast Kluyveromyces lactis. The...

1. RFLPs, used in the search for the Huntington's Disease gene, can be used to identify point mutations through which of the following mechanisms? Group of answer choices a. The mutation can occur in a restriction site, causing a change in the cutting pattern for restriction enzymes. b. The mutation can be silent in the coding for protein resulting in a different amino acid being inserted. c. The mutation can occur outside of a restriction site causing a change in...

1.) Two linked genes, A and B, are separated by 20cM. A man with genotype AB/ab marries a woman who is ab/ab. What is the probability that their first child will be Ab/ab? 2.) An individual has genotype Ab/aB. Gene loci A and B are 20cM apart. What is the proportion of expected progeny Ab/ab if a testcross is performed on this individual?

Two genes’ expression values follow a bivariate normal distribution. Let X and Y denote their expression values respectively. Also assume that X has mean 9 and variance 3; Y has mean 10 and variance 5; and the covariance between X and Y is 2. In a trial, 50 independent measurements of the expression values of the two genes are collected, and denoted as 1 1 ( , ) X Y , …, 50 50 ( , ) X Y ....
