WebDec 18, 2024 · Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences. Previously, genotyping would enable only partial sequences to be obtained.

WebFigure 1. Different types of natural selection can impact the distribution of phenotypes within a population. In (a) stabilizing selection, an average phenotype is favored. In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed. In (c) diversifying selection, two or more extreme phenotypes are ... Web12 years ago. A new hypothesis is that all Homo Sapiens originally had Dark Eyes (Brown) and that one individual about 6,000 to 10,000 years ago had a mutation which partially turned off the gene for Dark Eyes which reduced the amount of Melanin in the eyes. It is further believed that all people with blue eyes are descended from that individual.
