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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
