Evaluate the image below and discuss the information portrayed in Graph A, B and C
nataly862011 [7]

In A and B we see the number of phenotypes that can be found, in a case of polygenic inheritance, depends on the number of allele pairs involved

<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>.

What do scientists know about fossils found in deeper layers of rock compared to
shusha [124]

Answer:

They know that layering, or bedding, is the most obvious feature of sedimentary rocks.  This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air. That is kinda easy :D
