Definition | Term |
Diagram used to determine the possible traits an offspring can recieve | Punnett Square |
An Individual's observable traits | Phenotype |
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 |
Cross between 2 individuals identically heterozygous for one gene | Monohybrid Cross |
Effect in which one gene affects multiple traits | Pleiotropy |
An Allele that gets hidden or masked by the dominant Allele | Recessive |
