|---|---|---|---|---|---|
| Trait | A distinguishing characteristic passed down from parent to offspring
🗑
|
||||
| Monohybrid Cross | A genetic cross that only deals with one set of characteristics
🗑
|
||||
| Dihybrid Cross | A genetic cross dealing with two sets of characteristics
🗑
|
||||
| Cross-pollination | The fertilization of a flower with the pollen of another flower
🗑
|
||||
| Self-pollination | Pollination of a flower by pollen from the same flower
🗑
|
||||
| Dominant | The characteristic expressed even in the presence of a recessive gene
🗑
|
||||
| Recessive | Characteristic that is only expressed in the homologous recessive condition
🗑
|
||||
| Alleles | One of a pair of genes that have the same position on homologous chromosomes.
🗑
|
||||
| Homozygous/Purebred | Both alleles in one organism are the same (RR)(rr)
🗑
|
||||
| Heterozygous/Hybrid | Two different alleles at the same position on homologous chromosomes (Rr)
🗑
|
||||
| Incomplete Dominance | Occurs in F1 chromosome
Produces phenotype combination of the phenotype of the two parents
🗑
|
||||
| Phenotype | based on Genotype
The physical expression of an organisms genes
🗑
|
||||
| Genotype | The genetic makeup of an individual organism
🗑
|
||||
| Pedigree | A chart of the genetic history of a family over several generations
🗑
|
||||
| Sex-Linked Traits | Traits located on the sex chromosome
🗑
|
||||
| Gregor Mendel | Father of Genetics
Discovered self vs cross pollination
Discovered traits come from parents
Experimented with peas to test pure vs hybrid
🗑
|
||||
| Law of Dominance | parents with pure traits will only have 1 offspring with their form of the trait
🗑
|
||||
| Law ofSegregation | during gamete formation, the two alleles responsible for a trait separate from each other
🗑
|
||||
| Law of Independent Assortment | alleles for different traits are distributed to sex cells independently of one another
🗑

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.
