IN DRAGONS Wings = dominant; No wings = recessive 17 WINGS = ________ NO WINGS = ______ TOTAL = ________ 9 26 http://www.biologycorner.com/worksheets/hardy_weinberg_problemset_key.html

What is the frequency of the: RECESSIVE (no wings) allele? ______ DOMINANT (wings) allele? _______ HETEROZYGOUS individuals ______ HOMOZYGOUS DOMINANT individuals ? _______ HOMOZYGOUS RECESSIVE individuals ? _______ 9/26= .35 =35% 59% 0.59 = 59% 41% 48% 0.41 = 41% 0.17 = 17% 17% 0.48 = 48% 35% If you came back 50 years later and the frequencies of the recessive and dominant alleles in the population were the same, this population is IN HW equilibrium NOT in equilibrium This means the population IS EVOLVING IS NOT EVOLVING
