WebDifferent versions of a gene are called alleles—sometimes alleles can be classified as dominant or recessive. A dominant allele always results in the dominant phenotype. In order to exhibit a recessive phenotype, an individual must be homozygous for the recessive allele. Genes affect both physical and psychological characteristics. WebWhether a gene is recessive or not has to do with the relationship between two different alleles of that gene. A dominant allele is called such because it produces a product whose properties dominate over those of a recessive allele.
