genteic trait that appears only when both of its corresponding alleles are identical and in the absence of its dominant counterpart allele For example, the recessive trait of blue eyes will only appear in persons only if both parents pass on blue-eye genes Otherwise, a dominant brown-eye gene will subordinate the blue eye and the offspring will be brown -eyed
an allele that is present in the genotype of an organism but may be masked in the phenotype of that organism by the presence of a dominant allele Submitted by Amy Franzen, franzena@pilot msu edu
A genetic condition that appears only in individuals who have received two copies of a mutant gene, one from each parent 1
{s} (about inherited traits) not expressed due to a dominant trait inherited from the other parent (Genetics)
A relative term describing the relationship of one allele to a second at the same locus when an animal heterozygous for these alleles expresses the same phenotype as an animal homozygous for the second allele The second allele of the pair is considered dominant See Recessive in the MGI Glossary
a trait that is not physically expressed in heterozygotes In order for the trait to be expressed, there must be two copies of the allele
of genes; producing its characteristic phenotype only when its allele is identical
only expresses itself phenotypically when paired with another recessive gene; its expression is obscured by the presence of a dominant gene
A recessive gene produces a particular characteristic only if a person has two of these genes, one from each parent. Compare dominant. Sickle-cell anaemia is passed on through a recessive gene. a recessive gene is passed to children from their parents only if both parents have the gene dominant
a gene that affects a snake's appearance if it's present in the homozygous state A heterozygous snake carrying a mutated, recessive gene looks normal
A gene that is phenotypically manifest in the homozygous state but is masked in the presence of a dominant allele
