A genomic researcher is analyzing the genome of different species of raptors. She finds that a particular sequence in the Bald Eagle genome is identical to a sequence found in the Red Tailed Hawk, while most other sequences in those two genomes differ at many nucleotides. (The most recent common ancestor between Bald Eagles and Red Tailed Hawks was approximately 6.8 million years ago, which is plenty of time for mutation to generate DNA sequence variation.) Which of the following could explain the identical sequence in these otherwise differing genomes? a. The sequence encodes a protein critical for the production of feather color.
b. The sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function.
c. The sequence is from an intron of a gene that encodes a protein in connective tissue.
d. None of these

Apopulation of bears has genetic diversity. some of the bears have an allele that gives them thicker fur. due to climate change, the winters have gotten colder in their habitat. now the bears with thicker fur are becoming more common in the population. a.) which type of bear is selected for in the coldest ecosystem? b.) what must be the other allele for the type of fur, and what term would you use to describe the fact that the allele is becoming less common in the colder climate? c.) describe the change in the bear population in terms of changing allele frequencies and phenotypes d.) is this an example of natural selection
