By using a genetic diagram or a punnett square, we can show the the result of a cross between RR and rr.
The result of the genotypes should all be Rr.
This means all their offsprings should have the dominant trait being expressed.
Therefore, the percentage to this should be 100%.
The picture above is an example of using a punnett square finding the possible genotypes of the offsprings.

How can mutations change the gene pool of a population?

Dvinal [7]

Answer:

Explanation:

The changes in the gene pool occurs from the one generation to another this process is called as the microevolution. The allele frequencies in the gene pool change due to many processes such as gene flow, natural selection, genetic drift, and mutation. In mutation the genetic variations occurs in the genome of the organisms due to change in the genetic makeup of the organisms new traits are produced which are passed on to the new generation and this brings change in diversity of genes in the gene pool.
