Chromosome pairs, known as homologous chromosomes, are not identical but are similar in structure and size. Each pair consists of one chromosome inherited from each parent, carrying genes for the same traits, although they may have different alleles. This genetic variation contributes to the diversity of traits in an organism.

Which pairs of cells do not have identical chromosomes numbers in a given species of plants?

In plants, the gametes (such as pollen and egg cells) have half the number of chromosomes as somatic cells. This means that the pairs of cells that do not have identical chromosome numbers in a plant species are the gametes and somatic cells. Gametes have half the number of chromosomes as somatic cells due to the process of meiosis that reduces the chromosome number by half during gamete formation.
