codominance
|
A condition in which two alleles of a given gene have different phenotype effects, with both effects manifesting in organisms that are heterozygous for the gene
|
|
dihybrid cross
|
an experimental cross in which the plants used differ in two of their characters
|
|
genotypes
|
the genetic makeup of an organism, including all the genes that lie along its chromosomes
|
|
heterozygous
|
possessing two different alleles of a gene for a given character
|
|
homozygous
|
having two identical alleles of a gene for a given character
|
|
incomplete dominance
|
a genetic condition in which the heterozygote phenotype is intermediate between either of the homozygous phenotypes
|
|
Law of independent assortment
|
a random distribution of homologous chromosome pairs on differing sides
|
|
law of segregation
|
Differing characters in organisms result from two genetic elements (alleles) that separate in gamete formation, such that each gamete gets only one of the two alleles. also known as mendel's first law, this is one of the principles of inheritance formulated by gregor mendel
|
|
monohybrid cross
|
An experimental cross in which organisms are tested for differences in one character
|
|
multiple alleles
|
three or more alleles-alternative forms of a gene-occuring in a population
|
|
Parental generation
|
the generation that begins an experimental cross between organisms. Such a cross is used to study genetics and heredity of traits
|
|
phenotypes
|
A physiological feature, bodily characteristic, or behavior of an organism
|
|
polygenic inheritance
|
Inheritance of a genetic character that is determined by the interaction of multiple genes, with each gene having small additive effect on the character
