ANTH222 Lecture Notes - Mendelian Inheritance, Point Mutation, Allele
Document Summary
Variation occurs as a result of mutation. Meiosis/sexual reproduction- genes get reshuffled not created (crossing over, independent assortment, etc. ) Recessive alleles only show when in homozygous conditions. Evolution- change in allele frequency, happens at the population level (not individual) Three dimensions of variation: now vs. before (time period variation, here vs. 1-2% of dna produces proteins/genes (rna proteins etc. ) Regulatory sequences produce transcription factors that turn on/off genes that produce proteins. The difference between chimps and humans is form regulatory sequences and when they turn on/off protein genes.
