What is the effective population size of the Asian elephant
population in Periyar, southern India where poaching has resulted
in an adult sex-ratio of 6 males to 605 females? What would be the
effective size with a ‘normal’ adult elephant sex-ratio of 1:3 (204
males to 407 females) if the census count is held constant at 611
elephants?

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...

1a) For a population of bighorn sheep, the demographic data are as follows: the estimated effective population size for females is 100 and males is 10. What is the effective population size? 1b) how does the reproductive system in a species affect the effective population size? what would you expect in a polygamous system? what about a polyandrous system? describe one system that demonstrates how genetic drift has acted as a evolutionary force.

A gene at an autosomal locus in one individual in a population of 24 barn catsundergoes mutation to a new neutral allele. What is the probability that the allele eventually becomes fixed? What is the probability that it eventually becomes lost?What are the answers if the mutant gene is X-linked and the population consists ofequal numbers of males and females?’

Red-green colorblindness is an X-linked, recessive trait. Suppose a group of 100 female and 100 male astronauts is sent to colonize a planet. 20 of the males are colorblind. 10 of the females are colorblind, and 30 are carriers. If this population were to establish a randomly mating colony in regards to this trait, what would you predict the frequency of colorblind males to be in the population over time if it were to immediately achieve and remain in Hardy-Weinberg...

36. In X-linked recessive inheritance, which of the following is not true? A. They appear much more frequently in males vs. females. B. Genes for sexed linked disorders are usually carried on the X chromosome. C. Females are typically carriers of disease, but do not show an affected phenotype. D. Affected males can pass the gene to their daughters, but they (daughter) are usually unaffected. E. All of the above are true.

3. A trait determined by an X-linked dominant allele shows 100 percent penetrance and is expressed in 9 percent of the females in a population. Assuming that the population Is in Hardy-Weinberg equilibrium, what proportion of the males in this population express the trait? Show your work. (4 pts) *4. Individuals with the genotype ee are 22 percent less fit than individuals with the genotypes EE or Ee. If E is present in this population at a frequency of 0.65,...
