Answer:
Hypothalamus and anterior pituitary gland.
Explanation:
Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.
The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.
Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.
The type of inheritance pattern flower color exhibited in this example is incomplete domination (Intermediate).
<h3>
What is meant by incomplete dominance?</h3>
Incomplete dominance or partial dominance is gene expression in offspring based on phenotypic observations that mediate from crosses of parents with different and contrasting characters.
Why intermediate traits can appear in an individual?
An intermediate trait occurs when both heirs are equally strong. The two inheritors of nature are neither closed nor covered. On the other hand, the parents will cover each other because they are just as strong. Offspring with intermediate traits will carry the same combination of traits from both parents.
