Answer:
To have a 100% chance of having offspring with the recessive genotype, each parent's genotype must be homozygous recessive.
Explanation:
For a recessive trait to be phenotypically evident it is necessary that the two alleles that form it are recessive, that is, that they are recessive homozygous.
The presence of a single dominant allele in one parent will probably suppress the expression of the recessive gene in at least half of the offspring.
<u>For the offspring to be 100% recessive, both parents must have a homozygous recessive genotype</u>.
