The correct answer is that "for most clients, surgery is recommended only if non-surgical treatments have been unsuccessful." This is because of the guidelines involving medicine and surgery as well as guidelines involving the treatment of colitis. The question should have specified what type of colitis is the patient having, whether infectious or autoimmune. In infectious colitis, then surgery almost has no role and medical treatment with antibiotics as well as supportive therapy and fluid replacement are the only ones needed. In autoimmune colitis such as Crohn's disease or ulcerative colitis, while immunosuppressor drugs may have a role, surgery may be the mainstay of treatment especially those who are at risk of malignant degeneration.

Answer:
The correct answer is - segregation.
Explanation:
The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.
The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.
There always has to be a dominant allele
