Berikan dua keadaan yang menunjukkan sesuatu populasi mengalami evolusi menurut Hardy-Weinberg. Give two conditions that show a population is evolving according to Hardy-Wienberg ii. Tuliskan persamaan yang menunjukkan keadaan frekuensi alel dan genotip berada dalam keseimbangan. Write equation that shows conditions where allele and genotype frequency at equilibrium

Think about a population of 50 individuals. In this population there are 6 individuals that have a homozygous recessive genotype and 9 individuals have a heterozygous genotype. The gene exhibits complete dominance. What proportion of individuals exhibit a dominant phenotype? Check both your the way that you think of this and how you calculate this one. Write it out.
