Summary Introduction
Introduction:
Homologous genes are the genes that are inherited from the same ancestor by two different species. They can be similar in sequence. Phylogenetic trees are generally based on homology. It means that two different species have some characters that are similar because these two species have the same common ancestor.

Why are fruit flies considered a model genetic organism? Would humans fit this description?
Now that cloning is possible, should it be used to clone animals that are near extinction? What are the possible ramifications of this when it comes to genetic diversity and size of the gene pool?
