1

Sex determination occurs initially through the SRY transcription factor acting on:

	primordial germ cells
	anterior pituitary
	testes support cells
	ovary support cells
	mesonephric duct cells

2

The lower end of the mesonephric duct branches to form the:

	ureteric bud
	uterus bud
	urethral bud

	none of the above

3

The sequential development of the renal structures within intermediate mesoderm can best be described as:

	mesonephric duct, metanephros, mesonephros
	mesonephric duct, paramesonephric duct, metanephros
	uteric bud, ureter, urinary bladder

4

The sequential development of the genital system can best be described as:

	internal and external genital tract dependent upon primordial germ cell hormone secretion
	gonadal differentiation and hormone secretion determining internal then external tract development
	mesonephric duct hormone secretion forming genital ridge then internal and external tract development
	internal tract determining gonadal then hormone secretion for external tract development
