  VSPA | Posted on : 02:56:24 PM on July 23, 2009 According to what i have read so far,: "Mutation is the alteration in chromosome structure and also an alteration in genes due to a change in DNA composition. It provides new alleles and therefore, underlines all other mechanisms that produce variations, the raw material for evolution". Hope this answers your question... |
