KCET · BIOLOGY · STD 12 - 4. Principles of Inheritance and Variation
In one of the hybridisation experiments, a homozygous dominant parent and a homozygous recessive parent are crossed for a trait. (Plant shows Mendelian inheritance pattern)
- A Dominant parent trait appears in \(F_2\) generation and recessive parent trait appears only in \(F_1\) generation.
- B Dominant parent traits appears in \(F_1\) generation and recessive parent trait appears in \(F_2\) generation.
- C Dominant parent trait appears in both \(F_1\) and \(F_2\) generations and recessive parent trait appears in only \(F_2\) generations.
- D Dominant parent trait appears in \(F_1\) generation and recessive parent trait appears in \(F_1\) and \(F_2\) generations.
Answer & Solution
Correct Answer
(C) Dominant parent trait appears in both \(F_1\) and \(F_2\) generations and recessive parent trait appears in only \(F_2\) generations.
Step-by-step Solution
Detailed explanation
(C) Dominant parent trait appears in both \(F_1\) and \(F_2\) generations and recessive parent trait appears in only \(F_2\) generations.,
When a homozygous dominant parent and homozygous female parent crossed for a trait, dominant parent trait appear in both \(F_1\) and \(F_2\) generation but recessive trait appear only in \(F _2\) genertaion.
When a homozygous dominant parent and homozygous female parent crossed for a trait, dominant parent trait appear in both \(F_1\) and \(F_2\) generation but recessive trait appear only in \(F _2\) genertaion.
