Zoology - Principles of Inheritance and Variation Question with Solution | TestHub
A homozygous tall pea plant with yellow pods is crossed with a homozygous dwarf pea plant with the green pods. The offsprings produced are selfed. In the F2generation, the ratio of plants having parental combinations to new combinations is
Options:
Answer:
Solution:
Genotype of homozygous tall plant with yellow pod is TTgg while genotype of dwarf plant with green pod is ttGG. All off springs they produce are hybrids TtGg (Tall with green pods). On selfing, they produce four types of plants: tall with green pod : tall with yellow pod : dwarf with green pod : dwarf with yellow pod in the ratio 9:3:3:1. The parental combinations tall with yellow pods and dwarf with green pods account to 6 out of 16 while recombinants tall with green pods and dwarf with yellow pods account to 10 out of 16.
