Read the following statements :
Assertion (A) : Some children have characteristics that resemble their parents while others are markedly different from their parents.
Reason (R) : Working out how much of any characteristic is due to nature or genes and how much is due to nurture or environment is a complex issue.
Choose the correct option.

Correct option is A

The correct answer is (a) Both A and R are true but R is not the correct explanation of A.
Explanation:
The assertion correctly states the observation of heredity and variation, where offspring inherit traits but also show differences. The reason correctly identifies the nature vs. nurture debate as complex. However, the complexity of the debate (Reason) does not directly explain why children look like or differ from their parents (which is due to genetic recombination and specific inheritance laws).
Information Booster:
Assertion:
⇨ Heredity: The transmission of genetic characteristics from parents to their children.
⇨ Variation: Differences between individuals of the same species due to genetic mixing.
⇨ Genotype: The actual genetic makeup an individual receives from their parents.
⇨ Phenotype: The observable physical or behavioral characteristics of an individual.
⇨ Inheritance: Specific traits are passed down through alleles following biological laws.
Reason:
⇨ Nature: Refers to biological influences, primarily genetics and hormones.
⇨ Nurture: Refers to environmental influences, including family, culture, and experiences.
⇨ Interactivity: Most traits are the result of a constant interaction between genes and environment.
⇨ Epigenetics: Study of how environmental factors can turn certain genes on or off.
⇨ Complex Issue: It is nearly impossible to isolate one factor from the other in human development.
