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.
Identical pairs of alleles are called homozygous alleles.
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.

A haploid cell is a sex-chromosome without pair. A diploid cell is a sex-chromosome with pairs . People have 22 chromosome pairs and 2 chromosomes they do not have pairs. A man has XY chromosomes and a woman XX chromosomes.
There are 46 chromosomes per cell, with 22 pairs and an XX pair for females or an XY pair for males.
Human cells typically have 46 chromosomes, which are organized into 23 pairs. Each chromosome in a pair contains identical components called sister chromatids, which are joined together at a region called the centromere.
When chromosomes are visible, they exist as replicated DNA, so each chromosome consists of two identical sister chromatids, which will be separated during mitosis to form two new identical daughter nuclei.
Chromosome pairs 1-22 are referred to as autosomes in genetics.
Identical pairs of alleles are called homozygous alleles.
