The genetic composition of a population is 40 homozygous dominant (RR), 360 heterozygotes (Rr)
and 600 homozygous recessive (rr).
What is the observed frequency of the homozygous dominant individuals?
[ Select]
What is the observed frequency of the "r" allele? [ Select ]
What is the expected frequency of the heterozygous genotype? [ Select ]
If the Chi-squared value for this system is 2.40, is the population in Hardy-Weinberg equilibrium?
Why? (note: the critical values for this test is 3.84), [Select ]
