carrier : usually do not exhibit a recessive trait, but they are capable of passing on a recessive allele for a trait
Characters : heritable features
chromosome map : shows the relative distance between a gene loci on a chromosome
codominance : another type of inheritance that differs from Mendel's findings because more than one allele is fully expressed
continuous variation : characters show range of differences when multiple genes act jointly
dihybrid : heterozygous for both traits
dominant allele : has an ability to mask the expression of the other allele
environmental effects : the degree to which many alleles are expressed depends on the environment
gene linkage : existence of several alleles on the same chromosome
gene locus : specific location of a particular gene on homologous chromosomes
genotype : alleles of an organism for a particular trait or traits, often designed by letters
Gregor Mendel : Austrian monk who experimented with pea plants
heredity : tendency for traits to be passed from parent to offspring
heterozygous : possessing unlike alleles for a particular trait
Homologous chromosomes : contain the same genes for the same traits; the same size, shape, and construction
homozygous : possessing two identical alleles for a particular trait
incomplete dominance : inheritance pattern in which the offspring has an intermediate phenotype, as when a red flowered plant and a white flowered plant produce pink flowered offspring
law of independent assortment : alleles of unlinked genes assort independently of each other during meiosis, so that the gametes contain all possible combinations of alleles
law of segregation : separation of alleles from each other during meiosis, so that the gametes contain one from each pair. Each resulting gamete has an equal chance of receiving either allele
multifactorial trait : trait controlled by polygenes subject to environmental influences. Each dominant allele contributes to the phenotype in an additive and like manner
phenotype : visible expression of a genotype
pleiotrophy : inheritance pattern in which one gene affects many phenotypic characteristics of the individual
polygenic inheritance : pattern of inheritance in which a trait is controlled by several allelic pairs. Each dominant allele contributes to the phenotype in an additive and like manner
punnett square : Grid used to calculate the expected results of simple genetic crosses
recessive allele : allele that exerts its phenotypic effect only in the homozygote. Its expression is masked by a dominant allele
recombinant gamete : new combination of alleles incorporated into a gamete during crossing-over
rule of multiplication : the chance of two or more independent events occurring together is the product of their chance of occurring seperately
sex linked traits : a trait associated with a gene that is carried only by the male or female parent
testcross : cross between an indicidual with the dominant phenotype and an individual with the recessive phenotype. The resulting phenotypic ratio indicates whether the dominant phenotype is homozygous or heterozygous
traits : alternative forms of a character
wild type : allele or phenotype that is the most common for a certain gene in a population
Xlinked : allele that is located on an X chromosome but may control a trait that has nothing to do with the sex characteristics of an animal
