Answers
Explanation:
1.Homozygous is a genetic condition where an individual inherits the same alleles of a gene from both the parents. Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents.
2.Speciation is the evolutionary process by which populations evolve to become distinct species.
3.evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.
Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. century workplace.
