Answer:
The correct answer would be B. the population is evolving.
It can be explained with the help of natural selection. It is a natural phenomenon by which organisms which are better adapted to the changing environment have better chances to survive and reproduce.
It leads to a change in the allele frequency of that trait in a population.
For example, in the given population, the allele frequency of red fur increases from 20 to 30 percent. That means the population is evolving to adapt to the changing environment.

Answer: - Predict an unknown genotype of a purebred dominant plant.
Explanation:
The genetic make up of the organism is called as the genotype. It describes the form of genes or allelic forms present in the organism. A test cross is used to determine the genotype of the organism. In this cross the organism with the unknown genotype is done with that of the organism with the known genotype. It also determines the fact that the organism is either homozygous dominant or hetrozygous.
On the basis of the above description, Predict an unknown genotype of a purebred dominant plant.
