- 1allelealternative forms of a gene that occupy a specific locus on a specific gene
- 2autosomal chromosomein humans, the 22 pairs of chromosomes that are not the sex chromosomes (XX or XY)
- 3autosomal dominantpattern of dominant inheritance that corresponds to a gene on one of the 22 autosomal chromosomes
- 4autosomal recessivepattern of recessive inheritance that corresponds to a gene on one of the 22 autosomal chromosomes
- 5carrierheterozygous individual who does not display symptoms of a recessive genetic disorder but can transmit the disorder to his or her offspring
- 6codominancepattern of inheritance that corresponds to the equal, distinct, and simultaneous expression of two different alleles
- 7dominantdescribes a trait that is expressed both in homozygous and heterozygous form
- 8dominant lethalinheritance pattern in which individuals with one or two copies of a lethal allele do not survive in utero or have a shortened life span
- 9genotypecomplete genetic makeup of an individual
- 10heterozygoushaving two different alleles for a given gene
- 11homozygoushaving two identical alleles for a given gene
- 12incomplete dominancepattern of inheritance in which a heterozygous genotype expresses a phenotype intermediate between dominant and recessive phenotypes
- 13karyotypesystematic arrangement of images of chromosomes into homologous pairs
- 14mutationchange in the nucleotide sequence of DNA
- 15phenotypephysical or biochemical manifestation of the genotype; expression of the alleles
- 16Punnett squaregrid used to display all possible combinations of alleles transmitted by parents to offspring and predict the mathematical probability of offspring inheriting a given genotype
- 17recessivedescribes a trait that is only expressed in homozygous form and is masked in heterozygous form
- 18recessive lethalinheritance pattern in which individuals with two copies of a lethal allele do not survive in utero or have a shortened life span
- 19sex chromosomespair of chromosomes involved in sex determination; in males, the XY chromosomes; in females, the XX chromosomes
- 20traitvariation of an expressed characteristic
- 21X-linkedpattern of inheritance in which an allele is carried on the X chromosome of the 23rd pair
- 22X-linked dominantpattern of dominant inheritance that corresponds to a gene on the X chromosome of the 23rd pair
- 23X-linked recessivepattern of recessive inheritance that corresponds to a gene on the X chromosome of the 23rd pair
