Assertion (A): Offsprings produced by sexual reproduction show variation.
Reason (R): Each offspring produced by sexual reproduction inherits all the genes from each parent.
Answer:
Offsprings produced through sexual reproduction show variation .
This is evident by observation of human beings .
While the basic body structure remains the same , the way we look, our height, facial features and other physical traits differ from our parents, and we are able to uniquely identify each other.
- This is because we inherit traits from our parents , but only the dominant phenotype (physical trait) from the combination is visible to us.
- Moreover, we do not inherit ALL our parent’s traits . From the 46 chromosomes, 23 are from the sperm, and 23 from the egg .
Hence, we observe variation.
The correct answer is C .
A is true but R is false.
