Botany-Mendel's Laws
NEET Botany Mendel's Laws Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): In the F2 generation of a monohybrid cross, the phenotypic ratio of tall to dwarf plants is 3:1. | Reason (R): The segregation of alleles during gamete formation is a random process, leading to a 50% chance of a gamete containing either allele.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The F2 phenotypic ratio of 3:1 is due to the dominance of the T allele over t, and the random segregation of alleles during gamete formation supports this inheritance pattern.
