In a cross between a black and a white cat, all members of the Fi generation are black. The F2 generation is made up of approximately 3/4 black and 1/4 white cat. Diagram this cross, showing the genotypes and phenotypes of the parents, F, and F2 generations. (i) What is the probability that the first two offspring will be homozygous and the third is white if an Ficat is test crossed? (ii)
