Gene mapping is the science that is used to identify and record the exact location of genes as well as the distance between them on a chromosome. This technology offers evidence of whether a disease that exists

A gene is the basic unit of heredity. Genes are made of DNA that eventually makes functional molecules named proteins. The genetic information that will pass to the next generation is contained in the DNA of genes. Genes are part of chromosomes. Humans have two copies of each gene (and ...

As is true of virtually every realm of the biological sciences, our understanding of speciation is increasingly informed by the genomic revolution of the past decade. Investigators can ask detailed questions relating to both the extrinsic (e.g. inter- and intra-population and ecological interactions...

A phylogeny is a branch of Biology that specially deals with Phylogenesis. An evolutionary tree is a visual demonstration of the evolution of species from its point of origin. A phylogenetic tree is a diagrammatic representation of the development of biological species. It is a branching repre...
There are four fundamental evolutionary forces that can influence the change of these traits, namely mutation, genetic drift, gene flow, and natural selection. Genetic drift, also known as random drift or random genetic drift, is the evolutionary mechanism whereby random fluctuation in allele ...
