(b) In the experiment conducted on pure-breeding varieties of oats, one with blackhulled grains and the other with white-hulled grains, the offspring (Fl) all had black-hulled grains. When Fl generations were crossed they gave F2 generation with the following phenotypes:
(i) 418 - black-hulled grains,
(ii) 106 — grey-hulled grains and
(iii) 36 - white-hulled grains.
Use the punnet square to show the gametes, genotype and phenotypes in each generation and suggest the genetic ratio.
