For each of the following situations explain how Hardy-Weinberg Equilibrium is a. altered and b. how each situation might lead to microevolution. Record your explanation. Only four golden mantled ground squirrels that live in a secluded valley escape death when the valley is hit by an avalanche.

Solution

a. before the avalanche hit the valley, the allele frequencies were different. but now, only four squirrels were left. since the genotype was not given for these squirrels, we cannot predict any value for allele frequencies. there are two possible cases:

case 1: the four may contain all the possible genotypes for a given specific gene. (such as \'AA\', \'Aa\' and \'aa\'). Or case 2: they may contain some genotypes (either 2 squirrels- \'AA\', 2 squirrels- \'aa\') If this is the case, the allele frequencies.

case 3: all of them may only a single genotype such as \'AA\'

b.

in case 1, it may some time to acquire all the genotypes and population.

in case 2: the population would attain equilibrium after some generations.

in case 3: the population would contain only a specific genotype.

b.
