Question | Answer |
---|---|
analysis of inheritance patterns to identify and characterize genes | Genetics |
biological factors that induce particular traits | Genes |
alternate forms of a given gene, inherited from different parents | Alleles |
the location on a chromosome, often used to refer to the gene at that site | Locus |
an allele which always determines the phenotype | Dominent |
an allele which only determines phenotype in the absence of a dominant allele | Recessive |
and entity that carries an mutation. The entity can be an allele, or an individual. | Mutant |
an allele, or individual, that is not mutated; occurring normally in nature. They are usually dominent | Wild Type Alleles |
the combination of alleles in an individual e.g. the genotype for someone with a Brown eye allele and blue eye allele is Bb | Genotype |
observable characteristics. The physical manifestation of the genotype. e.g. the phenotype of a Bb person is brown eyes. | Phenotype |
to carry both copies of the same allele, i.e. both dominant or recessive (BB or bb) | Homozygous |
to have different alleles, i.e. one dominant one recessive (Bb) | Heterozygous |
a homozygous individual | Homozygote |
heterozygous individual | Heterozygote |
a cross where one gene locus is tracked, e.g. Aa x Aa | Monohybrid Cross |
a cross where two loci are tracked, e.g. AaBb x AaBb | Dihybrid Cross |
the first generation produced in a series of crosses | Filial 1 |
the second generation produced in a series of crosses | Filial two |
inheritance of alleles at one locus does not influence inheritance at other loci | Independant assortment |
sex determining chromosome, X or Y | Sex chromosome |
any chromosome except X or Y | autosome |
a gene located on the X chromosome | X linked; sex linked |
A male who carries an X linked allele | Hemizygote |
any gene not located on X, or characteristic not associated with X | Autosomal |
a cross where three loci are tracked e.g. AaBbCc x AaBbCc | Trihybrid cross |
1:2:1:2:4:2:1:2:1 | F2 Genotypic Ratio; Dihybrid Cross |
9:3:3:1 | F2 Phonotypic Ratio; Dihybrid Cross |
1:2:1 | Monohybrid Genotype Ratio |
3:1 | Monohybrid Phenotype Ratio |
