Populations or species with low genetic diversity at many genes are at risk. When diversity is very low, all the individuals are nearly identical. If a new environmental pressure, such as a disease, comes along, all of the individuals within the population may get the disease and die.o measure the genetic diversity of a particular gene, scientists look at how many different versions of it (called alleles) are present in a population. For example, one gene may determine the flower color of a plant. Different alleles may exist for that gene (e.g., a pink allele, a purple allele, and a white allele).
