You are to show full working out and draw punnet squares.

a) If you perform a test cross between a plant that is heterozygous for both flower color (Rr) and plant height (Tt) with a plant that is homozygous recessive for both traits (rrtt), what would be the possible combinations of phenotypes and genotypes in the offspring?

b) In a co-dominance scenario where a black cat (BB) is crossed with a white cat (WW), resulting in offspring with black and white patches (BW), what would be the expected phenotypic and genotypic ratios if a test cross is conducted with one of the patchy offspring?

c) If you perform a test cross between a plant with red flowers (R) and a plant with white
flowers (WW) that exhibit incomplete dominance, resulting in pink flowers (RW), what would be the potential phenotypic and genotypic outcomes of the offspring?
