When a trait is influenced by multiple genes Epistasis
Having Identical alleles in a gene Homozygous
Relationship between 2 versions of a gene Codominance
In Chromosomal DNA, sequences of nucleotides repeated multiple times in a row Short Tandem Repeats
An allele having more than 2 forms within a population Multiple Allele Systems
Bell shaped Curve in a graph Bell Curve
The principle made by Gregor Mendel stating that when 2 or more characteristics are inherited, hereditary factors assort independently during gamete production. Law of Independent Assortment
The heterozygous offspring of a cross of 2 different species Hybrids
Location of a gene on a chromosome Locus
A cross between a homozygous recessive and an individual of unknown genotype Testcross
Effect in which one allele isn't fully dominant to the other, so the heterozygous phenotype is an intermediate blend between 2 homozygous phenotypes Incomplete Dominance
Masks or hides the recessive allele Dominant
Cross between 2 individuals identically heterozygous for two genes Dihybrid Cross
Having 2 different alleles of a gene Heterozygous
The set of alleles held by the chromosomes Genotype
All of the genes on a chromosome Linkage Group
Range of small differences on a shared trait Continuous Variation
The principle made by Gregor Mendel stating that 2 homologous chromosomes end up in different gametes during meiosis Law of Segregation
