WebGenes come in pairs (that is, are present in two copies in an organism). Genes come in different versions, now called alleles. When an organism has two different alleles of a gene, one (the dominant allele) will hide the presence of the other (the recessive allele) and determine appearance. WebGregor Mendel's principles of heredity, observed through patterns of inheritance in pea plants, form the basis of modern genetics. Mendel proposed that traits were specified by "heritable elements" called genes.
