Question

What can be the reason(s) for a change in allele and genotype frequencies in a population?

Please list at leat four separate reasons, with a brief explanation.

What is the ultimate source of new alleles?

Answer 1

Answer #1

Mutation- change in sequence of gene and so alter function

Immigration- it also add new allele to population

Emigration - it removes existing allele with going population

Variation- variation come due to geographic barrier ,mutat mut ,envi environmental condition etc.

genetic drift and bottle neck effect is also responsible for change in allele frequencies .

Ultimate sources of new allele is natural selection which act on all above point.

2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

You are studying a population of milkweeds and you find the following allele frequencies: f(A1A1) = 0.36 f(A1A2) = 0.48 f(A2A2) = 0.16 If the fitness of the heterozygote (w12) is 0.9 and the average fitness of the population is 0.916, what do we expect the new frequency of the heterozygote genotype to be in the next generation?
