The autonomic nervous system is involved in controlling a, c, d, e.
what is the Autonomic nervous system?
The peripheral nervous system's autonomic nervous system (ANS) is in charge of regulating critical processes like digestion, breathing, and heartbeat. In the acute stress response, it collaborates with the endocrine system to get the body ready for fight or flight.
Between the central nervous system and the internal organs, the autonomic nervous system acts as a relay. It regulates the exocrine and endocrine glands, smooth muscle, the heart, the lungs, and the heart. These organs are mostly under the autonomic nervous system's control, which is unconscious.
Hence from the above information, we get to understand that ANS helps to control systems, not in our control hence it will regulate all the given options except skeletal muscles as they are under control.

Since color blindness is a sex-linked recessive genetic disorder, it is carried by a X chromosome. Males (XY) are affected if they get the affected X from their mother, since males only have one X, and it is therefore always expressed. Females (XX), however, get one X from their mother and the other from their father. So both parents have to pass a color blind X to be affected (both alleles, by the definition of recessive).
Even though the mother is not affected, she's carrying it because her father was color blind. And the father is not affected. However, in Turner's Syndrome, one X is destroyed after fertilization, so the other X is the daughter's primary (only remaining) X. Note: Turners only affects females. Therefore, this is a rare situation in which a daughter gets affected by an X-linked recessive condition.
B is the correct answer Crossing over does not occur between genes
C. nerves and muscle fibers
