Question

If both parents are carriers of an recessive inherited trait, what are the chances that their child will express that trait?

Answer 1

The chances that the child will express that trait is 1/4 or 25%. Let the dominant trait be R and the recessive r.
A cross between Rr and Rr would yield RR, Rr, Rr and rr. Only RR would express the trait since its recessive.
Therefore chances =1/4 or 25%
