Hormone levels in the body is regulated by negative feedback mechanism. In this mechanism, a stimulus stimulates the release of a substances. After the effect of that substance its further release is inhibited. This can be understood by an example, the anterior pituitary gland stimulate the thyroid gland to release thyroxin and on increasing the thyroxin in the blood, feedback the hypothalamus and anterior pituitary to inhibit further release of thyroxin from thyroid gland.

Explanation:
Independent assortment of alleles of the genes during anaphase-I of meiosis-I requires that the genes should be present on different chromosomes. The genes that are present on the same chromosomes deviate from the independent assortment. These closely placed genes are called linked genes. They move from one generation to next together and do segregate randomly. This results in the generation of more proportion of the parental types in the progeny. The linked genes may be present on both autosomes and sex chromosomes.
