|---|---|---|---|---|---|
| Genotype | The genetic code of an organism represented by two alleles; 3 genotypes (homozygous dominant, homozygous recessive, heterozygous)
🗑
|
||||
| Phenotype | The physical appearance of an organism based on its genotype (eye color, height, seed shape, etc)
🗑
|
||||
| Punnett Square | A tool to solve genetic problems mathematically; determines the probability of the genotypes and phenotypes of offspring
🗑
|
||||
| Recessive | An expression of a gene that is masked by a dominant allele; represented by a lowercase letter; This trait only appears when both alleles are present.
🗑
|
||||
| Homozygous (Pure/True-breeding) | A genotype with the same two alleles (both dominant OR both recessive)
🗑
|
||||
| Heterozygous (hybrid) | A genotype with two different alleles (one dominant and one recessive)
🗑
|
||||
| Allele | An expression of a gene; may be dominant or recessive; there are 2 alleles for every gene
🗑
|
||||
| Probability | The likelihood that an even will occur
🗑
|
||||
| Dihybrid Cross | A cross between 2 individuals with two traits (ex. flower color, plant height)
🗑
|
||||
| Monohybrid Cross | A cross between 2 individuals with one trait (ex. flower color)
🗑
|
||||
| Dominant | Describes an expression of a gene that is always expressed because it covers up the recessive form; represented by a capital letter
🗑
|
||||
| Law of Dominance | Mendel's law stating that when two alleles of an inherited pair is heterozygous, then, the allele that is expressed is dominant whereas the allele that is not expressed is recessive
🗑
|
||||
| Law of Segregation | Mendel's law stating that two copies of each gene are separated during meiosis when gametes are formed. Since organisms inherit 2 copies of each gene (one from each parent), only one copy of each gene can be donated to offspring;
🗑
|
||||
| Law of Independent Assortment | Mendel's law stating that alleles separate independently of each other during meiosis, which means different traits appear to be inherited separately. In other words, the presence of one trait does not affect the presence of another trait.
🗑

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.
