Completely confused, please help with an explanation
In garden pea plants the genes for height and
flower colour are on different chromosomes.
The allele T (tall) is dominant to the allele t
(dwarf) and the allele R (purple flowers) is
dominant to the allele r (white flowers).
A true-breeding tall plant with purple flowers
was crossed with a dwarf plant with white
The F1 generation were self-pollinated and 64
plants were obtained in the F2 generation.
How many of the F2 generation would be
expected to be tall with white flowers?
