For this particular question, we're told that we're looking at three different genotypes, and we're told that for every dominant allele we have, that adds 15 to the trait, and for every recessive allele that subtracts 16 from the trait.
00:15
So we're going to go ahead and list those genotypes.
00:19
And then we're just going to go through and assign a value to each allele.
00:23
So in the top one that we're looking at, i see a dominant, so it's plus 15.
00:28
Another dominant plus 15 another dominant another dominant this is a recessive so subtract six another dominant and another recessive and so once we have all of those written out you would just do that on your calculator 15 plus 15 plus 15 plus 15 minus 6 my 6 my 6 my 6 plus 15 plus 15 minus 6 and so you would come up with this positive 45 so that means according to the alleles here, you would take whatever the base is for this trait and you would add 45 to it.
01:08
And then we can do the same thing for these other genotypes.
01:12
You just go through and each allele at a time, you write out what it would do to this trait, or you could even do this directly on your calculator, save a little bit of time...
