Question:
Differentiate between X-chromosome and Y-chromosome with reference to –
length of non-homologous regions
type as per position of centromere.
Differentiate between X-chromosome and Y-chromosome with reference to –
length of non-homologous regions
type as per position of centromere.
length of non-homologous regions
type as per position of centromere.
Show Hint
X and Y differ genetically; non-homologous regions drive sex-linked traits, centromere position defines chromosome type.

Solution and Explanation
| Feature | X-Chromosome | Y-Chromosome |
|---|---|---|
| Length of Non-Homologous Regions | Longer (large non-homologous region) | Shorter (small non-homologous region) |
| Type as per Centromere Position | Metacentric / Submetacentric | Acrocentric |
Answer: X has longer non-homologous regions and is metacentric/submetacentric; Y has shorter regions and is acrocentric.
