- Homologous chromosomes
- Autosomes
- Centrosomes
- Non-homologous chromosomes
Hint:
The two chromosomes are of same length.
The correct answer is: Homologous chromosomes
- Identical chromosomes are also called as homologous chromosomes.
- The homologous chromosomes have same lengths and centromere positions.
- The homologous chromosomes have same gene at the same locus.
- Homologous chromosomes are not identical since one is derived from each parent.
