Document Summary
The maintenance and measurement of genetic variation do the math to show why genetic variability is important and how it came about. Neodarwinism - the harmonization of (mendelian) genetics and darwinian natural selection. Hated each other polymorphic subjects were used to study genetics in the field loci - that you sample; polymorphic - variable alleles are passed on in different combinations identify whether they increase, decrease or both, diversity. Two labs were struggling with how to measure genetic variability. Can look at the genes that control proteins. Grind up a piece, run it through a gel, dye specific proteins. Allonyms are different forms of the same protein. Can start counting genotypes at a particular genes. The more genes the more accurate your assessment. Can identify the heterozygous and separate from homozygous (needs co-dominance) Hypothesis 2: running out of diversity (cannot adapt to new diversity) widespread species are more polymorphic people started using different markers to use to study genetics.
