An alternate form or variety of a gene. The alleles for a trait occupy the same locus or position on homologous chromosomes and thus govern the same trait. However, because they are different, their ...
dominant allele
Anthropology; Physical anthropology
An allele that masks the presence of a recessive allele in the phenotype. Dominant alleles for a trait are usually expressed if an individual is homozygous dominant or heterozygous.
mutation
Anthropology; Physical anthropology
An alteration of genetic material such that a new variation is produced. For instance, a trait that has only one allele (A) can mutate to a new form (a). A mutation can be a change in DNA bases or ...
recessive allele
Anthropology; Physical anthropology
An allele that is masked in the phenotype by the presence of a dominant allele. Recessive alleles are expressed in the phenotype when the genotype is homozygous recessive (aa).
mutagen
Anthropology; Physical anthropology
An agent that can cause a mutation to occur. Various kinds of chemicals, viruses, and radiation have been identified as mutagens.
