Question

A recessive gene causes a certain breed of goats to "faint" when they
are startled. If two goats that faint are
bred together, what percent chance do their offspring have of
fainting?
A. 100%
B. 50%
C. 25%
D. 0 %

Answer 1

C. that would be a punnentt square

Answer 2

Answer:

A 100%

Explanation:

R = non-fainting gene

r = fainting gene

If both parents faint, the must have the "rr" gene combination.

So when setting up your Punnett Squares, each of the 4 blocks would have "rr" within them.

Parent 1 = rr      Parent 2 = rr
