The process of speciation.

Introduction:

The speciation is the process, through which the different species have evolved from a single ancestor. The speciation occurs when the organism genetic composition is changed according to the environment, they are living in.

Expert Solution & Answer

Explanation of Solution

For the process of speciation, there should be a change in the environment of the members of a single species. The main factor, which can be use to detect the occurrence of the speciation involves the reproductive incompatibility from the previous species.

The three steps of speciation are given below:

1. Divergence: in this step, members of a single species are diverged into different groups. Some of the gene pool of the population become isolated from each other.

2. Evolution of new traits: depending on the environment, the separated gene pool evolves certain characters, which make them genetically different from the species they have evolved.

3. Reproductive incompatibility: due to the changes in the genetic composition, the species cannot mate with the members of the species, from which it has evolved.

Conclusion

The three steps of speciation are, divergence of the members, adaptation and evolution according to the new environment and evolution of reproductive incompatibility.

There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?
