Answer:
X-linked/Sex-linked recessive inheritance
Explanation:
<em>The most likely mode of inheritance of the trait is an X-linked recessive inheritance.</em>
The sex chromosome of a male is XY while that of a female is XX. The Y chromosome is hypothesized not to carry any allele ordinarily. Hence, a male child only needs to inherit one affected allele to become affected for recessive X-linked traits.
During gamete formation, the sex chromosome of the male segregates into X and Y gametes while that of the female segregates into X and X gametes. During fertilization, the X gamete of the male is usually inherited by the female while one of the X gametes of the female is usually inherited by the male.
<u>Assuming a father is affected for an X-linked recessive trait, the affected X chromosome will be passed to a female child and such a child would be a carrier, rather than being affected since she requires the two X chromosomes to be affected in order to exhibit the trait. </u>
<u>The affected X chromosome is thus passed to her male child according to the law of inheritance of the sex chromosome. Hence, the grandson of the affected man inherits the trait through the daughter of the affected man.</u>
Answer:
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.

Explanation: There are two types of digestion in the body. Mechanical and Chemical. Mechanical digestion occurs in the mouth (chewing). Amylase is present in saliva, and begins the breakingdown those substances in the mouth and continues to break them down in the esophagus and stomach.
