4 sources of genetic variation
formation of new alleles, altering gene number or position, rapid reproduction, sexual reprduction
hardy weinberg equilibrium equation?
p^2 + 2pq + q^2 =1
“point mutation” ? example?
change in one base of a gene, i.e. sick cell
The duplication of genes is due to errors in what?
meiosis
if gene duplications do not have severe effects it can persist over generations… this leads to?
accumulation of mutation, expands genome i.e.) smell receptors
three mechanisms in sexual reproduction that contribute to shuffling of genes
crossing over, independent assortnment of chromosomes, fertilization
When only two alleles and 2 genotypes possible, what equation is true?
p+q=1
