|---|---|---|---|---|---|
| DNA- | molecule contains the information that determines the traits that a living thing inherits and needs to live
🗑
|
||||
| Chromosomes- | in an eukaryotic cell, one of the structures in the nucleus that are made up of DNA n protein
🗑
|
||||
| Cell cycle- | Life cycle of a eukaryotic cell
🗑
|
||||
| Interphase- | A period of a cell cycle during which activities such as cell growth and protein synthesis occur without visible signs of cell division
🗑
|
||||
| mitosis- | process of cell division that forms two new nuclei, each of which has the same number of chromosomes
🗑
|
||||
| Cytokinesis- | the division of the cytoplasm of a cell.
🗑
|
||||
| homologous chromosomes- | chromosomes that have the same sequence of genes and the same structure
🗑
|
||||
| Meiosis- | a process in cell division during which the number of chromosomes decreased to half the original number by two divisions of the nucleus which results in the production of sex cells.
🗑
|
||||
| asexual reproduction- | reproduction that does not involve the union of sex cells and in which one parent produces offspring that are genetically identical to the parent
🗑
|
||||
| sexual reproduction- | reproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents.
🗑
|
||||
| fertilization- | the union of a male and female gamete to form a zygote.
🗑
|
||||
| heredity- | the passing of genetic material from parent offspring
🗑
|
||||
| Genes- | one set of instructions for an inherited trait
🗑
|
||||
| Alleles- | one of the alternative forms of a gene that governs a characteristic, such as hair color
🗑
|
||||
| genotype- | the entire genetic makeup of an organism also the combination of genes for one or specific traits
🗑
|
||||
| Phenotype- | an organisms appearance or other detectable characteristics
🗑
|
||||
| Dominant- | in genetics, describes an allele that is fully expressed whenever the allele is present in an individual
🗑
|
||||
| Recessive- | Recessive-
🗑
|
||||
| incomplete dominance - | a condition in which two alleles are expressed such that the phenotype of a heterozygous individual is an intermediate of the phenotypes of the two homozygous parents
🗑
|
||||
| codominance- | a condition in which two alleles are expressed such that the phenotype of a heterozygous individual is a combination of the phenotypes of the two homozygous parents
🗑
|
||||
| punnett square- | a graphic used to predict the results of a genetic cross
🗑
|
||||
| ratio- | a comparison of two numbers using division
🗑
|
||||
| probability- | the likelihood that a possible future event will occur in any given instance of the event
🗑
|
||||
| pedigree- | a diagram that shows the occurrence of a genetic trait in several generations
🗑

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.
