Allele | One member in a pair gene pair that controls characteristics, such as eye color or hair color.
🗑
|
||||
Chromosome | A threadlike structure of nucleic acids and protein that carries genetic information in the form of genes.
🗑
|
||||
DNA | Deoxyribonucleic acid, makes up chromosomes and the carries genetic information.
🗑
|
||||
Dominance | Situation in which one allele is expressed over a second allele.
🗑
|
||||
Gene | A portion of a DNA molecule that serves as the basic unit of heredity.
🗑
|
||||
Genotype | The genetic makeup of an individual organism expressed with letters.
🗑
|
||||
Genetic Crossing | The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent.
🗑
|
||||
Mitosis | Asexual cell division where one parent cell divides and produces two identical daughter cells
🗑
|
||||
Heterozygous | A pair of genes where one allele is dominant and one allele is recessive.
🗑
|
||||
Homozygous | A pair of genes where both alleles are dominant or both are recessive.
🗑
|
||||
Hybrid | An animal or plant resulting from a cross between genetically unlike individuals.
🗑
|
||||
Independent Assortment | Mendel's law that states that traits are transmitted to offspring independently of one another.
🗑
|
||||
Phenotype | The physical appearance of an organism as distinguished from its genetic makeup.
🗑
|
||||
Punnett Square | A type of grid that can indicate all the possible outcomes of a genetic cross.
🗑
|
||||
Recessive | An allele whose phenotype is masked when paired with a dominant allele.
🗑
|
||||
Segregation | Mendel's law that states that organisms inherit one allele for each trait from each parent due to allele pairs separating during gamete production.
🗑
|
||||
Meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell
🗑
|
||||
Purebred | A homozygous trait where BOTH alleles are the same. Ex. TT or tt
🗑
|
||||
Meiosis | When gametes are created and result in one allele in the sex cells.
🗑
|
||||
Codominance | When two dominant traits show in an offspring
🗑
|
||||
incomplete dominance | When their is a blending of traits creating an entirely new 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.
