For offspring to have a recessive trait, what has to be true? (a) both parents had to give a recessive trait to their offspring
(b )one parent had a recessive allele to pass on but the other parent only had dominant alleles
(c) both parents had only dominant alleles

A. both parents had to give a recessive trait to their offspring

Explanation:

Both parents need to give a recessive trait because if there's any dominant ones, it'll overpower the recessive ones

d. in sexual reproduction, offspring have more chromosomes than

explanation:
