Phytochemistry 69— A tribal level phylogeny of Lake Tanganyika cichlid fishes based on a genomic multi-marker approach. Direct methods, such as the sequencing of B chromosomes isolated through flow sorting or microdissection, have a high rate of contamination [ 1418 ] and are only possible in a few organisms.

What happens if something causes more or less chromosomes to develop? Contact Us. Every human cell has 23 pairs of chromosomes for a total of 46 aside from sperm and egg cellswhich each contain only 23 chromosomes. The head region contains a cap-like covering called an acrosome.

Some chromosome abnormalities do not cause disease in carriers, such as translocationsor chromosomal inversionsalthough they may lead to a higher chance of bearing a child with a chromosome disorder.
