Question

A population has 0.01 BB individuals, 0.18 Bb and 0.81 bb individuals. Assume 200 offspring are born, but only 50% of the bb individuals make it to adulthood, the other genotypes fair just fine. What is the frequency of the B allele in the next generation? Group of answer choices 0.716 0.03 0.01 0.83 Suppose a founding population has an allelic frequency not typical of the original population. Which of the following effects would most likely lead to homogenization? Group of answer choices no mutations within either population genetic drift within the founding population migration between the original and founding populations random mating within the founding population In Europe, there is a high frequency of the disease Muscular Atrophy- even though there is reduced fitness of carriers. What explanation is given for the maintenance of this polymorphism? Group of answer choices Mutation rate creating new alleles balanced with selection against the allele is enough. Heterosis, or heterozygote advantage. Selection in the past has left some people that are immune to the disease. Migration of individuals from another population keeps introducing the trait, even though there is selection against the trait in Europe.

scenario-1-selection-against-a-recessive-allele-consider-a-gene-evolving-in-a-population-with-two-alleles-a1-and-a2-in-the-current-generation-the-frequency-of-allele-a1-in-the-population-is-11725

Scenario 1. Selection Against a Recessive Allele Consider a gene evolving in a population with two alleles, A1 and A2. In the current generation, the frequency of allele A1 in the population is given by p = 0.5 and that of allele A2 is given by q = 0.5. A1 is the dominant allele, and the fitness of each of the genotypes (as measured by the frequency by which the zygotes of that phenotype survive to adulthood), are as follows: A1 A1 ω11= 1.0 A1 A2 ω12 = 1.0 A2 A2 ω22= 0.7 Answer the following questions based on this information. Which genotype has the lowest fitness? What is the selection coefficient (i.e., strength of selection), s, against the homozygous recessive genotype? What is the current average fitness of the whole population? What will be the frequency of the dominant allele A1 in the second generation? (I.e., the next generation following the current one?) What will be the average fitness of the whole population in this subsequent generation?

Consider a population of 1,000 individuals at Hardy-Weinberg equilibrium. There are two loci, each with two alleles, in linkage equilibrium with one another. At the first locus the alleles "A" and "a" cause two distinct phenotypes; individuals who are "AA" or "Aa" are Alabaster whereas individuals who are "aa" are ebony. At the second locus the alleles "B" and "b" cause three distinct phenotypes. Individuals who are "BB" are robust, individuals who are "Bb" are medium and individuals who are "bb" are gracile. If we determine that there are 480 alabaster robust and 160 ebony robust individuals: (a) What is the frequency of the A allele? Round to nearest 0.01. (b) How many copies of the B allele exist in the population? Round to nearest integer. (c) What proportion of the population are ebony medium individuals? Round to nearest 0.01. (d) How many individuals will be homozygous at both loci? (e) If the environment suddenly changed and ebony individuals thereby gained a 10% increase to their fitness relative to alabaster, what would the frequency of the A allele be in the next generation? Round to nearest 0.001.

Consider a locus with two alleles - B and b. B is dominant, while b is recessive. There is no mutation. B has a selective advantage relative to b, so that the fitnesses of the three genotypes are BB = 1, Bb = 1, and bb = 1-s. In this case, s = 0.50, so that bb homozygotes have 50% fitness of heterozygotes and BB homozygotes. If the population has the following genotypic counts prior to selection of BB = 500, Bb = 250, and bb = 250, what is the expected change in the frequency of B after one generation with selection? Please give your answer to two decimal places.

00:01 Hello everyone.
00:02 So in this question the proportions given are a population has, here we are writing proportion and here we are writing individuals.
00:20 Right.
00:21 So it is given that a population is 0 .01.
00:28 So individuals are capital b b, capital b small b and the proportion given is 0 .01...
