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>.

The answer is Convergence of images behind the Retina
Convex lens converges light to a principal focus. The thickness of the lens determines the focal length (distance between the center of the lens and the principal focal point). Therefore, by evaluating the thickness of the convex lens, farsightedness, (an eye defect of convergence of images behind the retina) can be corrected by enabling images in the eye to form behind the retina.
