Describe the development of internal and external sexual in individuals who inherit XX sex chromosomes and no genes from a SRY region. Be sure to mention 1) secretion of follicle-stimulating, luteinizing, anti-Müllerian hormones; 2) gonads and the hormones and gametes they produce; 3) external sexual traits that are developed

Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.
Besides producing gametes (sperm and eggs), the primary male and female reproductive organs also produce sex hormones. The _____ and the pituitary gland control secretion of both.
Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
Label the early development stages shown in the following diagram.

Which of the following is true regarding the determinants of sexual development: the presence of the gene for HY antigen on the Y chromosome determines whether a testis develops from the gonadal ridge. the presence of MIS determines whether the Wolffian ducts develop. the presence of estrogen determines whether a vagina develops. the presence of DHT determines whether a prostate develops.
Describe, from fertilization, the major pathways of normal male sex development. Include the stages in which genetic sex, gonadal sex and phenotypic sex are determined.

Discuss whether the following individuals (1) have male or female gonads, (2) are phenotypically male or female (Wolffian or Muellerian ducts.
