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

4

The protein product of the gene SRY acts as a

  growth factor
  endocrine factor
  receptor protein
  transcription factor
