And finally we have this mating with this. So we have lowercase G, lower case g, so lowercase G, lower case G, lower case C, lowercase T. And so we form once again if we multiply one by zero four. So we have one multiplied by zero four gives a 0.4 probability. And so that means out of 1000 offspring, 400, about 400, we'll have this genotype here. So we see that in the case of part A, if the two genes are actually unlinked, not linked, then we have a one to one to one to one ratio of these genotypes. But in the case of these genes being linked, the ratio changes, the ratio becomes we have 40 to ten to ten to 40 or 40 to 40 to ten to ten.
