|
Law Of Segregation |
When any individual produces gametes, two copies of a gene separate so that each gamete receives only one member of the pair |
|
|
Test Cross |
A chart that determines whether a trait is homozygous or heterozygous dominant |
|
|
Dihybrid Cross |
A chart that shows a crossing of two different traits from two different individuals |
|
|
Law Of Independent Assortment |
when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together. |
|
|
Pedigree |
A chart that shows weather an allele is dominant or recessive |
|
|
Wild-type |
Gives rise to the predominant form of a trait |
|
|
Mutation |
An alteration made in DNA sequencing |
|
|
Polymorphic |
When the wild-type allele is present at a locus less than 99 percent of the time |
|
|
Incomplete dominance |
When neither alleles are dominant |
|
|
Codominance |
When two alleles at a locus produce two different phenotypes that both appear in heterozygous |
|
|
Epistasis |
One gene affects the expression of another |
|
|
Heritability |
The relative contribution of genetic versus environmental factors to the variation in a character in a population |
|
|
Genetic linkage |
the tendency of alleles that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. |
|
|
Recombinant |
a cell or organism whose genetic complement results from recombination |
|
|
Hemizygous |
When there is only one allele Ex Males Sex Chromosomes |
|
|
Heterozygous carriers |
When you have one dominant and one Recessive allele |
|
|
Plasmids |
Small extra DNA molecules in bacteria that carry genes involved in important metabolic processes |
|
|
Bacterial conjunction |
When prokaryotes reproduce asexually and transfer genes from one cell to another |
|
|
Recombination sequences |
The regional genes (V, D, J), used to generate T-cell receptors and Immunoglobulin molecules |
