Answer:

0%

Explanation:

Round = Dominant

Wrinkled = recessive

Recessive = r

Dominant = R

homozygous dominant = RR

homozygous recessive = rr

Heterozygous= Rr

Since both seeds are homozygous recessive (rr)

In your punnet square, one lower case r will go on the top and the left side

r r

r

r

Something like that.

Go across your four boxes and you will end up with;

rr, rr

rr, rr

In order for it to be round, at least one box would need to have to be a heterozygous(Rr) or be a homozygous dominant.
