The complete set of DNA within the nucleus of any organism is Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39 Learning Objectives. Describe the chromosomal makeup of a cell using the terms chromosome, sister chromatid, homologous chromosome, diploid, haploid, and tetrad. Human karyotype is represented by 46 chromosomes, whereas chimpanzees have 48 chromosomes [ 9 ]. In general, both karyotypes are very similar. However, there is a major difference corresponding to the human chromosome 2 Learning Objectives. Describe the chromosomal makeup of a cell using the terms chromosome, sister chromatid, homologous chromosome, diploid, haploid, and tetrad. Recognize the function and products of mitosis and meiosis. Compare and contrast the behaviors of chromosomes in mitosis and meiosis. Recognize when cells are diploid Key Points. A normal human karyotype contains 23 pairs of chromosomes: 22 pairs of autosomes and 1 pair of sex chromosomes, generally arranged in order from largest to smallest. The short arm of a chromosome is referred to as the p arm, while the long arm is designated the q arm The primary difference is that humans have one fewer pair of chromosomes than do other great apes. Humans have 23 pairs of chromosomes and other great apes have 24 pairs of chromosomes. In the human evolutionary lineage, two ancestral ape chromosomes fused at their telomeres, producing human chromosome 2. [5]

Humans have 23 pairs of chromosomes and other great apes have 24 pairs Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape. Chromosome 1 is the largest and is over three times bigger than chromosome The 23rd pair of chromosomes are two special The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living
