Question

Match List I with List II

List I (Gene interaction)	List II (Examples)
(A). Holandric genes	(I). Multiple effects of a single gene
(B). Pleiotropy	(II). Hypertrichosis
(C). Multiple alleles	(III). ABO blood types

Choose the correct answer from the options given below:

• (A) - (I), (B) - (III), (C) - (II)
• (A) - (I), (B) - (II), (C) - (III)
• (A) - (III), (B) - (I), (C) - (II)
• (A) - (II), (B) - (I), (C) - (III)

Hint:

Holandric genes are on the Y chromosome, pleiotropy is one gene with many effects, and multiple alleles give ABO groups.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Different types of gene behaviour have standard examples in genetics.

Step 2: Match each term
Holandric genes are Y-linked and pass from father to son; hypertrichosis is an example: (A) \(\rightarrow\) (II).
Pleiotropy is the multiple effects of a single gene: (B) \(\rightarrow\) (I).
Multiple alleles are three or more forms of a gene, as in ABO blood types: (C) \(\rightarrow\) (III).

Step 3: Select the option
The combination (A)-(II), (B)-(I), (C)-(III) is option (D).

Final Answer:
The correct matching is (A)-(II), (B)-(I), (C)-(III). \[ \boxed{\text{(D) }\text{(A)-(II), (B)-(I), (C)-(III)}} \]
