|---|---|---|---|---|---|
| homozygous | , you've got a pair of matching alleles, which are the two genes that control a particular trait. If both your alleles that determine blood type are O, — and you've got type O blood.
🗑
|
||||
| heterozygous | refers to a pair of genes where one is dominant and one is recessive — they're different. Like all words with the prefix hetero, this has to do with things that are different — specifically genes.
🗑
|
||||
| punnett square | is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used to determine the probability of an offspring having a particular genotype.
🗑
|
||||
| tetrad | a group or set of four.
🗑
|
||||
| phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
🗑
|
||||
| genotype | the genetic constitution of an individual organism.
🗑
|
||||
| homologous | (of chromosomes) pairing at meiosis and having the same structural features and pattern of genes.
🗑
|
||||
| karyotype | the number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
🗑
|
||||
| probability | the extent to which something is probable; the likelihood of something happening or being the case.
🗑
|
||||
| meiosis | cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
🗑
|
||||
| gene map | a record of the DNA sequence of a gene.
🗑
|
||||
| crossing over | the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
🗑
|
||||
| independent assortment | formation of random combinations of chromosomes in meiosis and of genes on different pairs of homologous chromosomes by the passage according to the laws of probability of one of each diploid pair of homologous chromosomes
🗑
|
||||
| incomplete dominance | refers to a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype.
🗑
|
||||
| haploid | (of a cell or nucleus) having a single set of unpaired chromosomes.
🗑
|
||||
| diploid | (of a cell or nucleus) containing two complete sets of chromosomes, one from each parent.
🗑

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.
