Recessive (Anthromorphemics)

A genetically determined characteristic that is expressed only in the homozygous recessive condition.

Recessive (Anthropology)

A genetically determined characteristic that is expressed only in the homozygous recessive condition.

Recessive (Bioinformatics)

Any trait that is expressed phenotypically only when present on both alleles of a gene (cf dominant).

Recessive (Biology)

The allele overshadowed by the dominant allele.

Recessive (Biotechnology)

A phenotype that is expressed in organisms only if it is homozygous for the corresponding allele.

Recessive (Evolution)

An allele (A) is recessive if the phenotype of the heterozygote (Aa) is the same as the homozygote (aa) for the alternative allele (a) and different from the homozygote for the recessive (AA). The allele (a) controls the heterozygote's phenotype and is called dominant. An allele may be partly, rather than fully, recessive; in that case, the heterozygous phenotype is nearer to, rather than identical with, the homozygote for the dominant allele.

Recessive (Fossils)

An allele (A) is recessive if the phenotype of the heterozygote (Aa) is the same as the homozygote (aa) for the alternative allele (a) and different from the homozygote for the recessive (AA). The allele (a) controls the heterozygote's phenotype and is called dominant. An allele may be partly, rather than fully, recessive; in that case, the heterozygous phenotype is nearer to, rather than identical with, the homozygote for the dominant allele.

Recessive (Genetics)

A gene that only produces its affect when both copies present are identical. A recessive gene trait will be passed on to children with only a 1 in 4 chance.

Recessive (Genetics and Genealogy)

A genetic trait or disorder that appears only in individuals who have received two copies of the recessive gene, one from each parent. Compare to Dominant.

Recessive (Hamster)

Refers to a gene that is masked unless there are two of the same gene present. In genetics these genes are denoted with lower case letters.

Recessive (Huntingtons Disease)

A term used to describe the degree of penetrance of an allele relative to other alleles of the same gene. A recessive trait is only expressed when there are two recessive alleles present. If a dominant allele and recessive allele are both present, the dominant trait will be expressed instead.

Recessive (Microbiology)

Allele that determines phenotype only when homozygous; does not affect phenotype when heterozygous with a dominant allele.

Recessive (Veterinary)

Requires a copy of the gene from both parents to exhibit the trait. Having only one copy of the gene makes the dog a carrier of the trait, and he will never exhibit the trait - unless the gene is located on the ‘X’ or sex chromosome. sarcoma - tumor formed of connective tissue cells: bone cartilage, muscle, blood vessel, or lymphoid tissue.
