Pretend down syndrome is a recessive trait and is represented by ss. 80% of affected ss people cannot have children. However, As and AA people are not affected. (AA being homozygous dominant for no trait, As being Heterozygous for trait)
Based off of 10,000 people,
AA = 7561
As = 2416
ss = 23 (With down syndrome)
a) What are the genotype, allele, and the phenotype frequencies?
b) Is this population in HWE (Hardy-Weinberg Equilibrium?) Please include work and reason why, I actually need to learn this for my test coming up.
Also, please use the chi-square distribution
