In a particular recessive genetic disorder, you find the allele frequency for this recessive allele in a population is 0.02. Assuming the population is in Hardy-Weinberg Equilibrium over the last generation, which of the following are possible statements about this population? Select all that apply. Select one or more: a. This genetic disorder could display severe and potentially fatal health complications only in individuals above 50 years of age. b. Most of the recessive alleles are found in heterozygous individuals. c. Any individuals in this population that are homozygous recessive are sterile. d. The population under investigation could have been formed by a founder event several hundred years ago.

Option B and C

Explanation:

When a population is said to be in Hardy Weinberg's Equilibrium, it is assumed to obey the following assumptions -

a) There is random mating among the organism

b) The mating should not be selective and in order to achieve so the population size must be infinite

c) There should be no loss or gain of allele thereby assuring that there is no selection, mutation, migration etc.

d) Also there must be no crossing among organism belonging to different generation

With all such assumptions, the allele frequencies will remain either constant thereby producing infertile recessive homozygous species or fertile heterozyous species.

Hence, option B and C are correct
