Question

(a) Two pea plants with green pods, $G g \times G G$ , were crossed. Complete the given Punnett square to show the results of this cross.
(b) What percentage of the offspring produced by this cross will most likely have green pods?

Solution

Given: GG and Gg are both green pods. This means that G is dominant and g is the recessive allele.
The given Punnet square-
Gg ----> G g
GG
G GG Gg
G GG Gg

The given progeny are GG, GG, Gg, Gg.
Since G is the dominant allele, so all the progenies will have green pod. Hence, 100% of the progenies have green pods.

Q. The punnett square shown below represents the pattern of inheritance in dihybrid cross where a plant, true breeding for tallness and green pods is crossed to a plant which is dwarf and yields yellow pods. Assuming that the dominant and recessive allele for tallness and dwarfness is T and t respectively and the dominant and recessive allele for yielding green pods and yellow pods is G and g respectively, study the F1 self cross given below:-
