What is the role of variation in evolution If heterozygosity is reduced what happens to the potential for evolution? The phenotype and genotype of a population is due to a mosaic of random and directed processes some of these have to do with history.some are related to adaptation etc. As completely as possible,discuss the role of chance and direction in evolution and in determining the phenotype of a population
