|| Cirrect! '''Thecal cells''' (female) and  '''interstitial cells''' (male) both form the sex hormone secreting cell population in the gonads. Leydig cells and interstitial cells are 2 names for the same cell in the testis. Primordial germ cells exist in both sexes and do form oocytes, but this is not what the question asked. The ductus deferens is the male internal genital tract formed from the mesonephric ducts.

Sex Determination Interactive Component

Attempt the Quiz - Sex Determination

Here are a few simple Quiz questions that relate to Sex Determination from the lecture and practical.

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

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

2 The cells in the adult male and female gonad forming from equivalent primordial cells in each sex are:

  Sertoli cells and thecal cells
  Leydig cells and interstitial cells
  primordial germ cells and oocytes
  thecal cells and interstitial cells
  ductus deferens and mesonephric ducts

3 The genes for testes-determining factors are located on the:

  short arm of the Y chromosome
  long arm of the Y chromosome
  short arm of the X chromosome
  long arm of the X chromosome
  both the X and Y chromosomes contain these genes
