Due to following reasons Neurospora is used as a genetic tool :

• Fastest growing in vitro, can be grown in minimal media.

• Due to its haploid nature it can express both dominant as well as recessive traits.

• Analysis of genetic combination is facilitated by the ordered sequence of the products in the form of eight ascospores [result of meiosis and mitosis].

• Release of ascospores per ascus takes place systematically i.e. one by one, so that single ascospores in an orderly sequence can be isolated in successive single spore culture.

• All the seven chromosomes of Nuerospora are either telocentric and achrocentric. Hence genes can be easily mapped.
