Notes: 9/14 Molecular Anthropology
Variation continues to be generated in our cells. Dominant DNA traits.
DNA could be transcript wrong. This could cause mutation which causes variation. Mutation is
the main part of variation.
Sexual reproduction tends to reshuffle things so the offspring get new traits of each parent.
Does not reproduce new genes, just shuffles them. The ultimate source of mutation is variation.
Proportion of Different Alleles
A pair of homologous chromosomes along the chromosomes are sections of DNA called
genes. Only 2% produces proteins. The other 98% was called “junk DNA”.
Alleles are different variations of the genes. When they
