The model organisms and significance of Neurospora in studying biochemical genetics. Introduction: Beadle and Tatum in the year 1941 used Neurospora (a fungus ) to study biochemical processes governed by genes and thereafter came up with “one gene, one enzyme” hypothesis. They demonstrated link between information coded in the genes and the end product of their expression.

Question

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.
