Focus on the evolution of horn size in the Bighorn sheep population from 1950 to present. What would you predict would happen if hunting were discontinued for bighorn sheep in a large population?

a) Genotype frequency of H2H2 and H1H2 would increase.

b) We would only see genetic drift, but not evolution by natural selection on horn size.

c) There would be a new mutation for large horns because the females would prefer to mate with males with large horns.

d) There would be a large amount of gene flow between the population where hunting was not allowed and nearby populations where hunting was still allowed.

e) Over time, we could see an increase in the H1 allele frequency.

Leroy Sims · Answer 1

The correct answer is option e) "Over time, we could see an increase in the H1 allele frequency".

Explanation:

The bighorn sheep (Ovis canadensis) is a species that is a very attractive for hunters because of its long horns. This negative human influence has make that bighorn sheep with long horns struggle to survive and reproduce. Horn size in bighorn sheep is determined primarly by a gene called HRN, which has two alleles H1 (for long horns) and H2 (for smaller horns). if hunting were discontinued for bighorn sheep in a large population we can predict that over time, we could see an increase in the H1 allele frequency, because in this population bighorn sheep with long horns will have better chances of surviving.

Dillon · Answer 2

The correct option is "Over time, we could see a rise in the H1 allele frequency"

Explanation:

Normally, bighorn sheep populace had a higher recurrence of individual with bigger horns because of sexual choice. Nonetheless, later on, illicit trophy chasing diminished the quantity of bighorn sheep with huge horns as bigger horn yields higher money related advantages. Development implies that a change in allelic frequencies has occurred. On the off chance that chasing isn't permitted, on the other hand we can anticipate an ascent in the recurrence of sheep's with huge horns (encoded by H1 allele) because of sexual determination (guys with bigger horns can discover female mates and leave offsprings).
