When godfrey hardy and wilhelm weinberg described the factors that affect genetic equilibrium, they first had to define what it meant for a population to be in genetic equilibrium. in order to imagine a state of genetic equilibrium, what assumption did they have to make?
a. mating must occur randomly
b. mutations must be only beneficial
c. genetic drift must occur at a steady rate
d. populations must not be geographically isolated

Explanation:

Godfrey Hardy and Wilhelm Heinberg equilibrium law or equation state that genotype and allele frequencies will remain constant form generation to generation in the absence of any evolutionary influences.

According to their law proportion will be at equilibrium if these five assumption hold true-

1. No genetic drift

2. A closed population

3. Mutation don't happen

4. No natural selection

5. Random matting patterns.

tissue

explanation:

it is actually formed by geoup of cells which is tissue
