NEET Solved Paper 2018 Question 14

Question: Which of the following pairs is wrongly matched? [NEET - 2018]

Options:

A) XO type sex determination Grasshopper

B) ABO blood grouping Co-dominance

C) Starch synthesis in pea Multiple alleles

D) T.H. Morgan Linkage

Show Answer

Answer:

Correct Answer: C

Solution:

    • XO type sex determination in Grasshopper is correctly matched. In grasshoppers, males have one X chromosome (XO) and females have two X chromosomes (XX).
  • ABO blood grouping is an example of co-dominance, where both A and B alleles are expressed in the phenotype.
  • Starch synthesis in pea plants is not an example of multiple alleles. It is typically controlled by a single gene with two alleles.
  • T.H. Morgan is known for his work on linkage and genetic mapping in Drosophila (fruit flies), so this is correctly matched.

Therefore, the pair “Starch synthesis in pea - Multiple alleles” is wrongly matched.
