Genetic Diversity Is Rampant:
-Genetic diversity is rampant as a result of mutation.
-Heterozygosity – the proportion of individuals that are heterozygous at a locus (H = 0-1).
-Allozyme – distinct variants of the same enzyme (similar amino acid sequence); thought to reflect
neutral genetic variation.
-New alleles arise by point mutations
-New alleles form from mutations during mitotic or meiotic events of the germ (reproductive) cell line.
-Evolution is the consequence of new alleles that are passed down to offspring.
Mechanisms Of Evolution:
-Population Genetics – the study of how allel
