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.
Sometimes sweetbreads from calves are called veal sweetbreads or sweetbread of veal but veal is the meat from a calf and not a type of animal, and all sweetbreads come from young animals, unless you consider the pancreas a true sweetbread, which I'll get to. The point is, the term veal sweetbreads is a bit redundant.ometimes sweetbreads from calves are called veal sweetbreads or sweetbread of veal but veal is the meat from a calf and not a type of animal, and all sweetbreads come from young animals, unless you consider the pancreas a true sweetbread, which I'll get to.
