A: Answer 1 As Tall (T) is dominant to short (t). By crossing two plants that are heterozygous for purple flowers, there is probability of 75% of the offsprings bearing purple flowers Explanation: Let us consider a cross between two plants heterozygous for purple flowers. What does that mean? For eg., in roses, the allele for red colour is dominant over the allele for white colour. If a pure-breeding purple-flowered pea plant is crossed with a pure-breeding white-flowered pea plant, all the offspring have purple flowers. The capital letter is generally used for dominant allele and small letter is for recessive allele. It is not unusual for roses to "change color." A minor change occurs when cooler weather intensifies pink-to-red shades, or age and hot weather fade them. 50%. This would lead to a 50% chance of the offspring having a phenotype of pink. So, TT = Homozygous dominant, Tall Tt = Heterozygous.
