dalvyx [7]

Answer:

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.

What hypothesis did Darwin investigate by studying the breeding of pigeons with distinctive traits?
siniylev [52]

Answer:

New species can appear gradually through small changes in an ancestral species.

Explanation:

The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.
