Humans have 23 pairs of chromosomes. by contrast, chimpanzees have 24 pairs of chromosomes and lack any pair resembling the long human chromosome 2 pair; instead, chimpanzees have two pairs of medium-sized chromosomes, each of which resembles parts of human chromosome pair 2. what is the most likely explanation for these differences and similarities in the human and chimpanzee genomes?

The communal antecedent of human being and chimpanzees had 24 pairs of chromosomes and at some fact in the heredity two chromosomes bonded end to end in which provided that nearly discerning benefit. In addition to biology, in humans the embryotic cell and fetal forms of hemoglobin have higher affinity for oxygen than of adults. This is in line to non - identical genes that yields dissimilar versions of the globin throughout fetal progress.
