What can a deficiency of growth hormone during bone formation cause? what can a deficiency of growth hormone during bone formation cause? decreased osteoclast activity inadequate calcification of bone increased osteoclast activity decreased epiphyseal plate activity?

The deficiency of growth hormone during bone formation would cause a decreased proliferation of the epiphyseal plate cartilage. Growth hormone is a peptide hormone secreted by the pituitary gland under the control of the hypothalamus. It directly through IGF-I stimulates osteoblasts proliferation and activity, promoting bone formation. In addition it also stimulates osteoclast differentiation and activity, promoting bone resorption. Therefore, growth hormone is an important hormone in bone formation. 

Incomplete dominance.

Explanation:

Mendel is known as the father of genetics. He had explained the different inheritance pattern present in different organisms. The Mendel explained the law of segregation, law of independent assortment and concept of dominance.

The incomplete dominance may be defined as the inheritance pattern in which the dominant trait is unable to express it self completely in the heterozygous condition and blending traits are produced. Here, the red color is unable to express itself in the heterozygous condition and produce pink color.

Thus, the correct answer is option (E).
