Given a diploid sexual population of mammals where mutation, selection and migration do not occur, and where these individuals mate at random within a population, First explain what effective population size means relative to a census population size. Then, if a population of 200 individuals is composed of 140 females and only 60 males, what is its effective population size (Ne) across the following parts of a genome due only to this difference in the proportion of each gender: At an autosomal locus? At an X-linked locus? For a mitochondrial DNA gene? For a Y linked gene?

This are the questions you need to answer: In mammals, males often have greater variance in reproductive success than females, as a result of sexual selection. How will this alter the effective levels of allelic variation in genes on the autosomes, the X chromosome, the Y chromosome and the mitochondrial genome? What other factors may influence the genetic diversity in these different parts of the genome? Discuss this question and potential answers with one another by posting your answers on...

you are studying a population of sexual, diploid insects. one particular trait, wing size, is controlled by a single locus with two alleles. The allele for narrow wing size is dominant (N) and the allele for wide wing size is recessive (n). The population you are studying is comprised of 83 NN individuals, 90 Nn individuals, and 83 nn individuals. What is the EXPECTED FREQUENCY OF THE DOMINANT ALLELE (N) AFTER SELECTION? Assume that w11=0.9, w12=1, and w22=0.7. i dont...

The bighorn sheep (Ovis
canadensis) is a species of sheep native to North America named for
its large horns. These horns can weigh up to 14 kg (30 lb), while
the sheep themselves weigh up to 140 kg (300 lb). The sheep live in
harems, groups of one male and multiple females. Populations of
bighorn sheep have inhabited Alberta, Canada for thousands of
years. In bighorn sheep, males fight each other by banging their
large horns together and males that...

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”.?
