Question:
Which of the following conditions correctly describes the manner of determining the sex in the given options?
Which of the following conditions correctly describes the manner of determining the sex in the given options?
Show Hint
XO sex determination is common in insects like grasshoppers, where absence of a second sex chromosome leads to male development.
Updated On: Jan 13, 2026
- Homozygous sex chromosomes (ZZ) determine female sex in birds.
- XO type of chromosomes determine male sex in grasshoppers.
- XO condition in humans determines female sex.
- Homozygous sex chromosomes (XX) produce male in \textit{Drosophila}.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In grasshoppers, the presence of only one sex chromosome (XO) leads to male development, while the presence of two (XX) results in females. This is a well-documented mode of sex determination in insects.
