Question 19

Consider a diploid population with 17 alleles at a single locus. How many possible genotypes are there? For
heterozygotes, the order of the alleles doesn't matter (so, treat Aa and aA as the same genotype).
The formula is slightly different than what was shown in Dr. Eckert's video, as it seems that repetition (ie homozygoes)
weren't taken into account.
You'll want to use this formula:
(r +n – 1)!
r!(n – 1)!
-
(if you cannot see the image, it's (r+n-1)!/r!(n-1)! where r is the same as k in the video).
For more info, here's a helpful website: (http://www.mathsisfun.com/combinatorics/combinations-permutations.html 2 )
You can still use the other formula if that is what you're most familiar with - you just need to add in the extra set of
homozygotes once you get your answer.
