Evolution Questions

Post by jolileia » Tue Feb 28, 2006 3:47 pm

Could anyone help me with this question plz? In a New Mexico Horned toad population there are albino toads at a frequency of one albino out of every 400 (1/400 = 0.0025) toads. Assume that this population is in Hardy WEinberg equilibrium. If this is an qutosomal recessive trait, what is the estimated frequency of the albino allele in this population?
Thank you so much

To do this problem, you have to understand some basic relations inherent to Hardy-Weinberg. The most important ones to use here are that q squared is equal to number of recessive individuals, and q=number of recessive alleles.

You started out right, 1/400=.0025 recessive individuals. This is equal to q squared. Taking the square root of .0025 will equal the number of recessive alleles, which is .05.

Is that all that you had to do for that problem?
