Q1. Black coat colour in cocker spaniels is dominant, at the same time as redcoat colour is recessive; a single (solid) colour pattern is dominant, as multi-colour pattern is recessive. A solid black male is mated to a solid red femal and produces a litter of six pups: two solid black, two solid red, one black and white, and one red and white. Find out the genotypes of the parents and their pups. Use Punnett Squares to demonstrate your answers

Q2. What did Mendel observe in the F2 offspring that showed him that alleles for seed shape segregate separately of those for seed colour?
