When a nerve impulse reaches the end of an axon, the axon terminal released ACh into the synaptic cleft. 2. ACh diffuses across the cleft and attaches to the ACh receptors on the sarcolemma of the muscle fiber. 3. ACh binding triggers electrical events that ultimately generate an action potential.

vlada-n [284]

Answer:

1)

  • frequencies of light-colored mice  ≅ 0.74
  • frequencies of dark-colored mice ≅ 0.26

2)

  • frequencies of light-colored mice ≅ 0.13
  • frequencies of dark-colored mice ≅ 0.87

3)

  • q² = 0.74
  • p² = 0.02
  • 2pq = 0.24      

4)

  • q² = 0.13
  • p² = 0.4
  • 2pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.
