| Allele | One of the possible types of a gene. Most genes have a dominant and recessive one.
🗑
|
||||
| Autosome | Any chromosome that is not a sex chromosome.
🗑
|
||||
| Codominance | Is when two genes are evenly shown
🗑
|
||||
| Dihydrid | An organism that is heterozygous for 2 traits
🗑
|
||||
| Dominant Allele | It is more influential over the recessive allele
🗑
|
||||
| Genotype | An organism's unique genetics
🗑
|
||||
| Heterozygous | having a recessive and dominant allele. Two differents ones
🗑
|
||||
| Homozygous | “Homo” Having the same alleles
🗑
|
||||
| Monohybrid | hybrid that is heterozygous for one trait
🗑
|
||||
| Multiple Allele | There are more than 2 alleles
🗑
|
||||
| Phenotype | appearance that is the way it is because of the environment and genotype
🗑
|
||||
| Punnet Square | a machine used to forecast the product of easy genetic crosses
🗑
|
||||
| Recessive Allele | innate factor shown in phenotype but only when genotype is homozygous
🗑
|
||||
| Sex Chromosome | chromosome that decides sex so either male XY or female XX
🗑
|
||||
| Sex-linked Trait | a certain trait that is with the sex chromosome but not to do with sexual stuff
🗑
|
||||
| Test Cross | crossing of the dominant and recessive phenotype
🗑
|
||||
| Apoptosis | the cell dies because a lot of cellular events have pushed the cell to dying
🗑
|
||||
| Cell Cycle | a cycle that has cell growth as well as division
🗑
|
||||
| Centriole | Is cell organelle. Found in pairs. Can organize spindle fibres during division
🗑
|
||||
| Centromere | area where sister chromatids bind to each other where fibres attach
🗑
|
||||
| Chromatin | Holds DNA. Is what chromosomes are made of
🗑
|
||||
| Chromosome | Hold your genes. See during division
🗑
|
||||
| Crossing-Over | transfer of genes between homologous chromosome .Makes offspring unique
🗑

🗑
|
||||
| Diploid(2n) | double # of chromosomes in gametes
🗑
|
||||
| Chromosome Number | characteristic # of chromosome in cell in certain species
🗑
|
||||
| Gamete | sexual reproduction cell that makes zygote
🗑
|
||||
| Haploid(n) Chromosome Number | haploid number (n) is the # of chromosomes in a gamete
🗑
|
||||
| Homologous Chromosomes | Chromosomes that pair up for meiosis
🗑
|
||||
| Meiosis | a type of cell division used for sexual reproduction
🗑
|
||||
| Mitosis | cell division where daughter has same genetic makeup. Used for growth and repair.
🗑
|
||||
| Nondisjunction | homologous chromosomes failing to split during meiosis
🗑
|
||||
| Somatic Cell | Any cell that is not a reproductive cell
🗑
|
||||
| Synapsis | homologous chromosomes pair in meiosis in prophase 1
🗑

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.
