Pollen from a red – flowered plant A was used to pollinate white flowered plant B, the seeds from which produced 157 red-flowered plants. When a red flowered plant C was pollinated by a white-flowered plant D, the resultant seeds gave rise to 84 red-flowered plants: and 91 white flowered plants. Assuming that plants A, B, C, and D were all of the same species and that flower colour in that species is controlled by a single pair of genes.
Using R for dominant gene and r for recessive gene, write down the genotypes of the following.
i)Plant A
ii)Plant B
iii)Progeny of A x B cross
iv)Plant C
v)Plant D
vi)Red flowered progeny of C x D cross.
