Neurospora is used as genetic material because

  • A.It has short life cycle of 10 days
  • B.The product of single meiosis can be easily analysed
  • C.Meiotic products are linearly arranged in the form of ordered tetrads
  • D.Is a diploid fungus

Answer: A

Neurospora is favoured as genetic material because its life cycle is only about ten days.

It is also haploid, so every mutation shows at once, and the products of a single meiosis are held in order in the ascus, which lets crossing over be read directly. Beadle and Tatum used it for the one gene–one enzyme hypothesis.
