Focus on the evolution of horn size in the Bighorn sheep population from 1950 to present. What would you predict would happen if
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 is One difference between a fundamental niche and a realized niche
anastassius [24]
Fundamental niche is the job/role that one species can have in the environment .
The realized niche is the role of a species influenced by several factors in the environment.
Example:
The fundamental niche of Yellow Warblers is found in a spruce tree.
The realized niche of the Yellow warblers is when they are "forced" to share the spruce tree and remain in one particular area of the tree while other warbler species play defense different niches in other parts of the tree.

:v it is like :
•Fundamental niche: [yellow warbler] "I got my home, all for me..."
~new species arrive to the spruce tree~
•Realized niche: [yellow warbler] oh, shoot! I gotta stay in the upper part/move to the upper part as the others warbler "struggle" to get territory :v or they just choose their own . :v
