Question

Gene G recombines with gene T at a frequency of 7%, and gene G recombines with gene R at a frequency of 4%.

Draw two possible genetic maps for these three genes, and identify the recombination frequencies predicted for each map.

Hi, everyone. Here's our next question. It says the formula two to the nth power is used to determine the types of games where N is the number of heterozygous gene loci. The number of gametes that can be produced by a diploid organism that is heterozygous for six, low cy is choice A 18 b 36 C 12 or D 64. So we have our formula for the number of gametes that can, can be produced. And we know that that equals two to the nth power where N is the number of heterozygous gene loci. So for example, if we had an organism that was homozygous dominant for gene A heterozygous for gene B and heterozygous for gene C, we would not count gene A. Since it's not heterozygous, we would only count genes B and C and our N would equal two. Since those are the only two genes that are heterozygous. In this case, we're told right out from the problem that our organism is heterozygous for six loci. So in this case, the number of gametes that can be produced is equal to two to the sixth power. Since we know that N equals six and 2 to 6. Power equals 64. So our answer will be choice D 64 as the number of possible gametes that can be produced. That was a nice easy one for us. Hope to see you in the next video.
