It'd be the second answer, a virus, which attacks the white blood cells.

Explanation:
Let the traits for the black coat color be = BB
Let the traits for the brown coat color be = bb
Let the traits for heterozygous black coat color be = Bb
Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.
This implies that if two rabbits that are both heterozygous for black coat color cross together;
i.e Bb × Bb ;
The offspring will be (BB, Bb, Bb, bb)
BB (rabbits with black coat color) = 1/4
Bb (rabbits that are heterozygous for black coat color) = 2/4
bb (rabbit with brown coat color) = 1/4
Lets focus on ''bb'' ;
bb = 1/4 × 100%
= 25%
Answer:

Explanation:
So in a simple explanation yes they require energy:)
