2 D.4.1 Explain how the Hardy–Weinberg equation is derived. TT = p2 = freq of homoz domTt = pq = freq of heterozygotett = q2 = freq of homoz recPunnett Square... Tt x Ttp2 + 2pq + q2 = 100% (1)p = freq of dominant alleleq = freq of recessive allele
3 D.4.2 Calculate allele, genotype and phenotype frequencies for two alleles of a gene, using the Hardy–Weinberg equation.Examples from class!
4 --a population is large --with random mating D.4.3 State the assumptions made when the Hardy–Weinberg equation is used. It must be assumed that:--a population is large--with random mating--constant allele frequency over timeThis implies--no allele-specific mortality--no mutation--no emigration--no immigration
