Ordered arrangement of chromosomes
WebChromosomes are arranged into homologous pairs, then sorted in descending size order. From this karyotype, we can see that the homologous pairs of autosomes are arranged in size order, descending from the largest (chromosome 1) to the smallest (chromosome 22). WebNormally, each pair consists of one chromosome from the mother and one from the father. There are 22 pairs of nonsex (autosomal) chromosomes and one pair of sex chromosomes. Paired nonsex chromosomes are, for practical purposes, identical in size, shape, and position and number of genes.
