Question

Select the INCORRECT statement.

• A. Female bird is heterogametic
• B. Holandric genes are present on non-homologous region of Y chromosome
• C. Queen bee and worker bees have haploid number of chromosomes
• D. Father is responsible for sex of the child in human beings

Hint:

{Honey bee females = diploid; males = haploid}.

Answer 1

The Correct Option is C

Step 1: Understanding chromosome number in honey bees.
Honey bees show haplodiploidy. Males (drones) are haploid, while females are diploid.

Step 2: Analysing the statements.
Female birds are heterogametic (ZW).
Holandric genes are located on Y chromosome.
Father determines sex in humans due to X or Y sperm.
Queen and worker bees are diploid, not haploid.

Step 3: Conclusion.
Thus, option (C) is the incorrect statement.
