PPT-Viral genetic mutation Viruses undergo genetic change by several mechanisms. These include

  Antigenic drift where individual bases in the DNA or RNA mutate to other bases Most of these point mutations are silent  they do not change the protein that the gene encodes . variation and fitness. Hardy Weinberg law. Assume a . gene . with two . alleles. A and B that occur with frequency p and q = 1-p. . What is the frequency after crossing?. According to the Hardy Weinberg law gene frequencies are constant.. By C. Kohn. Agricultural Sciences. Waterford, WI. 1. Species Change. The . traits of a species are primarily determined by the types of proteins made in its cells. . All proteins are made from amino acids, and different arrangements of amino acids result in different proteins. . Human chromosomes. Most cells in your body normally contain 46 chromosomes, organized into 23 pairs. In each of these 23 pairs, you've inherited one chromosome from your father and one from your mother. . . Trabelsi.
