If straight hair is dominant to curly hair, what genotype would you expect to see if the phenotype is curly?
A: Ss
B: ss

B: ss

Explanation:

Since straight hair is dominant it would be a capital S and curly would be a lower case s. If a straight hair gene was in the genotype it would block out the curly hair, so the only way to have curly hair would be ss.

The endocrine system is the system of glands, each of which secretes different types of hormones directly into the bloodstream (some of which are transported along nerve tracts[citation needed]) to maintain homeostasis. The endocrine system is in contrast to the exocrine system, which secretes its chemicals using ducts. The word endocrine derives from the Greek words "endo" meaning inside, within, and "crinis" for secrete.
