In many organisms sex is determined genetically. Often this is accompanied by chromosomal differences between the sexes. Chromosomes, structures made of proteins and coiled DNA, contain all the genetic information of an organism.
What Are Sweetbreads? ccording to the Larousse Gastronomique, sweetbread is the culinary term for the thymus gland (in the throat) and the pancreas (near the stomach) in calves, lambs and pigs. Larousse further states that thymus sweetbreads are elongated and irregular in shape while pancreas sweetbreads are larger and rounded. But sweetbreads are neither sweet, nor are they bread. The word sweetbread was first used in the 16th century, but the reason behind the name is unknown.
Sweetbread is the thymus gland of animals. It is a light meat that is firmer in texture than brains. The sweetbreads of veal are considered the best. Beef sweetbreads are rather fatty and coarse, but if well prepared, they will taste almost the same as veal.
