Web13 jul. 2014 · • Genetic drift is evolution that simply happens by chance due to sampling error. RANDOM FIXATION • Allele frequencies can drift between 0 and 1. • At 0 that frequency is lost • At 1 the allele is said to be fixed. Why is that? • Fixation is the elimination from a population all the alleles at a locus but one. WHAT IS HETEROZYGOSITY?
