|---|---|---|---|---|---|
| show | to determine the probability of 2 or more independent events occurring together, multiply the probabilities of each event happening separately
🗑
|
||||
| show | genetic material on a chromosome that contains the instructions for creating a particular trait
🗑
|
||||
| show | several varieties of a gene
🗑
|
||||
| show | location on a chromosome where a gene is located
🗑
|
||||
| show | each parent contributes a chromosome to the pair, they may contain different alleles
🗑
|
||||
| show | gene that is being expressed
🗑
|
||||
| show | gene that is not expressed
🗑
|
||||
| phenotype | show 🗑
|
||||
| show | represents the actual alleles
🗑
|
||||
| show | one member of each chromosome pair migrates to an opposite pole so that each gamete contains only one copy of each chromosome
🗑
|
||||
| show | the migration of homologues in one homologous chromosome to opposite poles does not affect the migration of homologues of other homologous pairs
🗑
|
||||
| monohybrid cross | show 🗑
|
||||
| show | two traits are being investigated
🗑
|
||||
| complete dominance | show 🗑
|
||||
| show | the combined expression of 2 different alleles produces a blending of the individual expressions of the two alleles
ex. wavy hair
🗑
|
||||
| show | both inherited alleles are completely expressed
🗑
|
||||
| show | ex. A, B, and O blood types
🗑
|
||||
| epistasis | show 🗑
|
||||
| pleiotropy | show 🗑
|
||||
| show | many genes shape a single phenotype
ex. height
🗑
|
||||
| linked genes | show 🗑
|
||||
| show | the more likely the two genes will cross over during synapsis
🗑
|
||||
| sex linked genes | show 🗑
|
||||
| example of sex linked gene | show 🗑
|
||||
| show | in females, one X becomes a barr body, so only the alleles on the active X chromosome are expressed
🗑
|
||||
| show | failure of one or more chromosome pair/chromotids to properly separate during meiosis or mitosis
🗑
|
||||
| polyploidy | show 🗑
|
||||
| point mutations | show 🗑
|
||||
| substitution | show 🗑
|

| insertion | show 🗑
|
||||
| aneuploidy | show 🗑
|
||||
| down syndrome | show 🗑
|
||||
| turner syndrome | show 🗑

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.
