Document Summary
Population genetics micro and macroevolution and taxonomy. Genome size does not correlate with evolutionary status nor is the number of genes proportionate with genome size. Humans have around 25, 000 and we are heterozygous at about 6% of those loci (this makes our general make up the same) Therefore we are capable of producing 21500 different possible combinations of those genes and this leads to lots of combination (this causes our differences) Gene locus is a address for a particular gene but the gene does not tell you what the dna is. A population is a community of individuals of a sexually reproducing species within which matings occur. They pass those genes along from one generation to the next. Population is the unit of evolution and the individual is the unit of selection (lives or dies and this determines what they pass on) Evolution change of allele frequencies over time:
