Answer:
A low secretion of luteinizing hormone(LH) in the normal male adult would cause B. decreased testosterone secretion.
Explanation:
For males the normal range is 1.24 -7.8 IU/L. If LH levels are below the normal range it may indicate a pituitary gland problem. Their pituitary gland may not be making enough LH which may lead to low testosterone.
Hypogonadism is a testicular disorder associated with low testosterone. Low testosterone levels can cause a variety of problems including diminished muscle mass & decreased sex drive as well as decrease in the physical as well as mental energy.
Luteinizing Hormone (LH) in males stimulates the production of testosterone. If LH secretion is low, it would result in decreased secretion of testosterone.
The secretion of Luteinizing Hormone (LH) plays a significant role in the male reproductive system. A low secretion of LH in a normal adult male most likely impacts the production of testosterone because LH stimulates the testes to produce this hormone. Therefore, a decrease in LH secretion would logically lead to a decreased secretion of testosterone (Option B). This decrease in testosterone can further lead to a reduction in sex drive, decreased muscle mass, and other sexual and physical changes.

The answer is; at least one gene, affecting at least one phenotypic trait, must change
This change, due to mutation, may result in an extreme trait in a small proportion of the population . If this extreme trait proves to be favorable with the environment it will continue to increase in the population with every generation. Eventually, the trait will become common in most individuals and the population will have speciated.
