Question

You are studying inheritance patterns in toads. You have two populations

of toads that you consider to be "true breeding." One population produces toads that are bumpy-backed and produce a lot of slime on their back. The other population have smooth backs and are relatively slime-free. You breed these populations together. You find that the first generation (F1) of offspring all exhibit dry, bumpy backs. Next, you breed this new toad generation among themselves to produce a second generation (F2).


Assuming that these genes follow the laws of Mendelian inheritance, what fraction of individuals will have a double homozygous dominant genotype in the F2 generation? Double refers to both genes being homozygous.
