Evaluate the image below and discuss the information portrayed in Graph A, B and C

<h3>Genetic distance</h3>

The knowledge of the genetic distance between genotypes of a population of interest is important for a breeding program, as it allows the organization of germplasm and a more efficient sampling of genotypes.

<h3>Gaussian</h3>

The normal distribution is a very useful model in statistics, and it would not come as a surprise as the sum of independent effects (or not very correlated effects) should, if there were many of them, normally distribute (always subject to certain assumptions).

With this information we can conclude that in graph <u>A</u> we see a higher frequency of medium-sized individuals, showing zygosity, and in <u>B</u>, <u>heterozygosity</u>.
