| genotype | an organism's genetic makeup; allele combinations
🗑
|
||||
| hybrid/heterozygous | an organism that contains 2 different alleles for a trait
🗑
|
||||
| natural selection | process - individuals that are better adapted to an environment are more likely to survive and reproduce to pass traits down to offspring
🗑
|
||||
| genetic engineering | process -genes from one organism are transferred into the DNA of another organism
🗑
|
||||
| inbreeding | crossing two individuals with identical or similar sets of alleles
🗑
|
||||
| evolution | gradual change in a species over many generations
🗑
|
||||
| adaptation | a trait that helps an organism survive and reproduce in its environment
🗑
|
||||
| heredity | passing of traits from parent to offspring
🗑
|
||||

🗑
|
||||
| hybridization | crossing two individuals with different sets of alleles
🗑
|
||||
| genes | factors that control traits
🗑
|
||||
| dominant | an allele whose trait always shows up in the organism when the allele is present
🗑
|
||||
| mitosis | process - produces 2 identical body cells each containing the same number of chromosomes as the parent cell
🗑
|
||||
| probability | likelihood that a particular event will occur
🗑
|
||||
| meiosis | process - produces four sex cells, each contain half the usual number of chormosomes
🗑
|
||||
| purebred/homozygous | produces offspring with the same form of traits as the parent; has two identical alleles for a trait
🗑
|
||||
| recessive | an allele that is masked when a dominant allele is present
🗑

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.
