Evolutionary Genetics

Genetics/ Evolution for Sex-Limited Genes

You have found a sex-limited gene that codes for male color in a Lake Victoria cichlid fish species. The dominant (R) allele codes for a red color and the recessive (r) allele codes for a greenish color. a) As you examine different populations of this species, you find that the R allele predominates in some populations and r

Australia, bird with three-toed feet

A. At one time the continent of Australia was connected to Asia. About 50 million years ago Australia became separated. It has many unusal animal not found elsewhere, such as the kangaroo and the koala bear. Using the concepts of geographic isolation the gene pool, explain why these animal developed. B.A species of bird with

Evolution is discussed.

Is "evolution" a proven fact or a theory? What other ideas compete with evolution to explain changes in populations? What are the differences between these competing ideas?

Viruses Mutations

The survival of viruses is a great example of natural selection and survival of the fittest. One such example is HIV. HIV reproduces very quickly (about 10 million new viruses per day. HIV lacks the proteins which repair mutations, and therefore there will be many mutations resulting from this rapid reproduction. The rapid rat

Evolution of Bacteria in Relation to Human Disease

Bacterial mutations are a great example of natural selection, especially those that cause the flu. But what happens when we can't develop a vaccine for a certain type of flu bacteria? If it turns out to be a deadly type, think about the population in the big cities that could be effected.

Believing in Biological Evolution

Please help with the following problem regarding evolutionary genetics. How would you respond to someone who tells you that he or she does not believe in biological evolution because it is "just a theory."
