Which of the following represent two regional populations exhibiting contrasting manifestations of adaptation to different environments according to the Allen's and Bergmann's rules? Group of answer choices Middle Eastern and Tibetan populations Alaskan and Sub-saharan populations Central American and West African populations Canadian and French populations

A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1 A2 genotype, and 123 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.

Given the following observed genotype frequencies (AA 0.45, Aa 0.16 and aa 0.39) for a gene that determines coat color with incomplete dominance in a population of lemmings.  Allele "A" results in a dark colored coat.  Allele "a" results in a light colored coat.  What percent of the population would possess a dark coat as their phenotype?

In cats, the black allele (B) is dominant over white allele (b). Given a population 2000 cats, 1680 black and 320 white, determine the allele frequency, the frequency of individuals per genotype and number of individuals per genotype.

Describe the similarities and differences between the stabilizing, directional, and disruptive selection models.

If the population has the following number of individuals: AA=3 Aa=2 aa=0 What is the frequency of each genotype? What is the frequency of each allele?

A gene has two alleles that are associated with body mass in an additive manner. The table below shows the mean phenotype for each genotype, along with the frequency of each genotype in a population. Use this information to answer the following questions.   A1A1 A1A2 A2A2 Mean mass (kg) 50 55 60 Frequency 0.01 0.18 0.81 a)  How much does this locus contribute to additive genetic variation?   b)A second locus (B) has two alleles (B1 and B2), which are also associated with body mass in an additive manner. Each copy of the B2 allele adds 2 kg of mass. The B2 allele is at a frequency of 0.6 in the same population as the A alleles are found. How much does the B locus contribute to additive genetic variation?
