-
dominant gene
gene that produces the same phenotype in the organism whether or not its allele identical
-
allele, allelomorph
(genetics) either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character
-
genetic marker
a specific gene that produces a recognizable trait and can be used in family or population studies
-
homeotic gene
one the genes that are involved in embryologic development
-
lethal gene
any gene that has an effect that causes the death of the organism at any stage of life
-
linkage group, linked genes
any pair of genes that tend to be transmitted together
-
modifier, modifier gene
a gene that modifies the effect produced by another gene
-
mutant gene
a gene that has changed so that the normal transmission and expression of a trait is affected
-
nonallele
genes that are not competitors at the same locus
-
operator gene
a gene that activates the production of messenger RNA by adjacent structural genes
-
oncogene, transforming gene
a gene that disposes normal cells to change into cancerous tumor cells
-
polygene
a gene that by itself has little effect on the phenotype but which can act together with others to produce observable variations
-
proto-oncogene
a normal gene that has the potential to become an oncogene
-
recessive gene
gene that produces its characteristic phenotype only when its allele is identical
-
regulator gene, regulatory gene
a gene that produces a repressor substance that inhibits an operator gene
-
repressor gene
gene that prevents a nonallele from being transcribed
-
structural gene
a gene that controls the production of a specific protein or peptide
-
suppresser, suppresser gene, suppressor, suppressor gene
a gene that suppresses the phenotypic expression of another gene (especially of a mutant gene)
-
transgene
an exogenous gene introduced into the genome of another organism
-
X-linked gene
a gene located on an X chromosome
-
Y-linked gene, holandric gene
a gene located on a Y chromosome
-
dominant, dominant allele
an allele that produces the same phenotype whether its paired allele is identical or different
-
recessive, recessive allele
an allele that produces its characteristic phenotype only when its paired allele is identical
-
homeobox, homeobox gene
one of various similar homeotic genes that are involved in bodily segmentation during embryonic development
-
CFTR, cystic fibrosis transport regulator
the gene that is mutated in cystic fibrosis
-
tumor suppressor gene
a suppressor gene that blocks unscheduled cell division
