Chapter 8 Mendel and Heredity
... There are alternative versions of genes. Today the different versions of a gene are called its alleles. When two different alleles occur together, one of them may be completely expressed, while the other may have no observable effect on the organism’s appearance. When gametes are formed, the alleles ...
