In squirrels, there are 3 potential phenotypes: Black, White, and Gray. A Gray squirrel is crossed with another Gray squirrel. What percentage will be Gray?

Explanation:

A gray squirrel can either have the same alllele GG or have two different allele Gg this will determine the percentage of the offspring that will be Grey.

For 2 parent with same allele

GG × GG

!

GG GG GG GG

all are grey 100%

For 2 parents with different allele

Gg × Gg

!

GG Gg Gg gg

75% will be grey

25% other color

its b. greenhouse gasses trap uv rays for heat so that the plants stay alive.

the statements that apply here about binary star system are

"have stars that might appear to wobble"

"often have one star that is brighter than other"

a binary star is a star system consisting of two stars revolving around their common barycenter. systems of two or more stars are called multiple star systems.
