Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion (A) : Analysis of the inheritance pattern of several traits in human beings can be done by the study of the family history of inheritance, known as pedigree analysis.

Reason (R) : The control crosses that can be performed in pea plants or some other organisms are not possible in the case of human beings.

In light of the above statements, choose the correct answer from the options given below.
 

Both (A) and (R) are true and (R) is the correct explanation of (A).  

Assertion (A) states that analysis of inheritance patterns in humans can be done through pedigree analysis, which is true. Pedigree analysis involves tracing the inheritance of traits through multiple generations within a family to understand patterns of inheritance and predict the likelihood of certain traits appearing in future generations.

Reason (R) provides an explanation for Assertion (A), stating that control crosses like those performed in pea plants are not possible in humans, which is also true. In organisms like pea plants, controlled crosses can be performed to observe specific patterns of inheritance. However, ethical and practical considerations prevent such controlled crosses from being carried out in humans. Therefore, pedigree analysis becomes an important tool for studying inheritance patterns in humans.
