Answer: Non-homologous chromosomes
Step-by-step explanation:
The overall length of the chromosomes and the placement of centromere are the two factors that required to same within the two pairs of chromosomes these chromosomes are considered as homologous chromosomes.
The non-homologous chromosomes can be defined as chromosomes that do not have the same overall length and placement of centromere is also not same. These chromosomes do not belong to the same pair or do not appear in the same pair.
The time of replication and banding pattern varies considerably in the non-homologous chromosomes.
