Summary Introduction
To characterize: The role of sex steroids in development.
Introduction: The glands of the endocrine system are termed as the endocrine glands. These glands directly secrete their secretions (hormones) into the blood without the use of any kind of ducts. Sex steroid hormones are secreted by the reproductive organs such as ovary and testes.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results:
