Pancreas is a organ located in the upper abdomen and adjacent to the small intestine. It performs two main kind of functions in the body:
1) Exocrine function: It helps in the digestion of food. It produces various enzymes such as amylase, lipase and trypsin which helps to digest carbohydrate, fats and proteins respectively.
2) Endocrine function: It produces hormonal insulin and glucagon which regulate the level of sugar present in the blood.
In human beings, the females have two X chromosomes and the males have one X and one Y chromosome. Therefore, the females are XX and the males are XY.
The gametes, as we know, receive half of the chromosomes. The male gametes have 22 autosomes and either X or Y sex chromosome.
Type of male gametes: 22+X OR 22+ Y.
However, since the females have XX sex chromosomes, their gametes can only have X sex chromosome.
Type of female gamete: 22+X
Sex determination in humans
Thus, the mother provides only X chromosomes. The sex of the baby is determined by the type of male gamete (X or Y) that fuses with the X chromosome of the female.
