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.

The possible statements about this population include:

The Hardy-Weinberg Equilibrium is simply a principle that states that the generic variation in a population will remain constant from a generation to the next generation when there are no disturbing factors.

Since the allele frequency for the recessive allele in a population is 0.02, then, most of the recessive alleles are found in the heterozygous individuals.

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

the missing space is phylum

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
