In a population of 1,000 individuals, 16% exhibit a recessive phenotype for a simple Mendelian trait. Assume the population meets Hardy-Weinberg expectations. Recall the two Hardy-Weinberg equations: p + q = 1 p2 + 2pq + q2 = 1 As we learned, each of those variable components represents something, which you should remember or have in your notes. What is the value of p2? I have input the 0 and the decimal for you, just type a whole number.  p2 = 0. What is the value of q? I have input the 0 and the decimal for you, just type a two-digit number.  q = 0. What is the value of p? I have input the 0 and the decimal for you, just type a two-digit number.  p = 0. What percentage of the population is expected to be heterozygous? Just write a whole number. % heterozygous = %
