Solution

The correct option is C Homologous chromosomes
  • Chromosomes are the structures found in the nuclei of the eukaryotic cells which are composed of both DNA as well as proteins.
  • Sister chromatids refer to the identical copies formed by the DNA replication of the chromosome, with both copies joined together with centromere.
  • Homologous chromosomes are the set of one maternal and one paternal chromosome that pair with each other inside a cell during meiosis. They contain the same type of gene at similar loci. They are the chromosomes that are similar in size, shape, gene and gene sequence.
So, the correct option is 'Homologous chromosomes'.
