Answer:
Most genes are identical, but dark and light rock pocket mice differ in one gene (Mc1r; 4:55). Data from Data Set 2 show that a mouse's genotype for the MC1R gene affects their fur color. Mice with two copies of allele 2 have the darkest fur.

The answer is 1/2.
If:
R - t<span>he dominant allele for red kernels
r - t</span><span>he recessive allele for yellow kernels
Then:
RR - dominant homozygote
Rr - heterozygote
rr - recessive homozygote
The cross Rr x rr will result in 1/2 of offspring with red kernels (Rr) and 1/2 of offspring with yellow kernels (rr):
Parental generation: Rr x rr
Offspring generation: Rr Rr rr rr
So, there are 2 out of 4 Rr offspring (2/4 = 1/2) and 2 out of 4 rr offspring (2/4 = 1/2).</span>
Since you didn't endow us with any choices, I'll list some possible explanations:
- Increase in food
- Decrease in predators/enemy species
- Resorted to a new niche
- Lower death rate
- Higher birth rate
I hope I helped!
Answer:
Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects.
