The amount of genetic variation by examining phenotypic variation was difficult because many traits, a complex interaction of many genes and environmental factors determines the phenotype

The amount of genetic variation in populations is commonly measured by two parameters –

1. The proportion of polymorphic loci

2. The expected heterozygosity is the proportion

The Death of a Gene

When a gene is duplicated, the new copy is often dead-on arrival (lacks the regulatory elements).

Gene Structure

The genes that code for many proteins are broken into pieces. These pieces—the exons—are separated by stretches of noncoding DNA—the introns

The current record holder is the gene Dscam in Drosophila. Alternative splicing of its 95 exons could potentially produce more than 38,000 kinds of proteins from this single gene.
