b. observations that the offspring of a cross made between the plants having two constrasting characters shows only one character without any blending
c. self-pollination of offsprings
d. cross-pollination of -generation with recessive parent
(b).
Phenotypic ratio Round : Round : Wrinkled : Wrinkled green
yellow-green yellow
9 : 3 : 3 : 1
Genotypic ratio 1 2 : 2 : 4 : 1: 2 : 1 : 2 : 1
Results of a dihybrid cross where the two parents differed in two pairs of contrasting triats seed colour and seed shape
