Chapter Ten Flashcards
Define Gene
A unit of hereditary information.
Define Allele
A version of a gene
Define Homozygous
Both alleles are the same
Define Heterozygous
Both alleles are different
Define Genotype
Genetic makeup of the cell
Define Phenotype
Visible or measurable trait
What is the Law of Independent Assortment?
Alleles of different genes will sort independently of each other during meiosis.
What is Incomplete Dominance?
Blending
What is Codominance?
Stripes/Polka Dots
What is Epistasis?
When more than one gene is required, a biosynthetic pathway. The precursor must be dominant for the next allele to be a possibility.
What is Gene Linkage?
When the genes you want to study are on the same chromosome.
What is a Test Cross?
Crossing an unknown dominant with a recessive homozygous.
What is the Locus?
The particular site on a chromosome where the gene is located.
Are there only two alleles for every gene?
No, there can be multiple alleles in a population.
What is Polygenic Inheritance?
Where the inheritance of many different genes contribute to the same character, usually for quantitative traits.
