What would be the expected frequencies of the homozygous dominant, heterozygous, and homozygous recessive (in that order) after 100 generations, assuming that no selection or other evolutionary processes are operating?

If no forces act on a population in Hardy-Weinberg equilibrium, proportion of genotypes will stay the same.

Explanation: The Hardy-Weinberg law provides an equation to relate the genotype frequencies and allele frequencies in a randomly mating population.

For two alleles, p and q, p + q = 1 and following mating, p² + 2pq + q² = 1 where p = homozygous dominant, pq = heterozygous and q = homozygous recessive.

Population in which allele frequencies do not change are in genetic equilibrium (zero evolution).

Hardy-Weinberg assumes five conditions;

1. Large population

2. Random mating

3. No immigration or emigration

4. No selection

5. No mutation

what are the choices?

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
