Colour in a type of flower is controlled by two genes thattogether lead to four unique colours of petals. The “A” allele ofgene 1 produces the dominant phenotype, blue flowers. The “B”allele of gene 2 produces the dominant phenotype, red flowers. Whenboth alleles occur together (A_B_) the flowers are yellow. In theabsence of either allele “A” or “B”, the flowers are mauve(aabb).

You are given some seeds that were produced by a yellow-floweredplant, and plant them in your garden. Once the plants have grownand the flowers are blooming, you find every one of the fourcolours in your garden. When you count the plants, you find 22yellow, 19 blue, 21 red, and 23 mauve. What can you deduce aboutthe genotypes of the parent plants? What colour (phenotype) was theother parent plant? Explain your answers in clear detail using acouple paragraphs. Use a Punnett square to help you understand.
