| Question | Answer |
|---|---|
| CHIASMATA | The X-shaped, microscopically visible region representing homologous chromatids that have exchanged genetic material through crossing over during meiosis. |
| CLONE | A lineage of genetically identical individuals or cells. |
| CROSSING OVER | The reciprocal exchange of genetic material between nonsister chromatids during synapsis of meiosis I. |
| DIPLOID CELL | A cell containing two sets of chromosomes (2n), one set inherited from each parent. |
| GENE | A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). |
| HAPLOID CELL | A cell containing only one set of chromosomes (n). |
| HOMOLOGOUS CHROMOSOME | Chromosome pairs of the same length, centromere position, and staining pattern that possess genes for the same characters at corresponding loci. One homologous chromosome is inherited from the organism's father, the other from the mother. |
| KARYOTYPE | A method of organizing the chromosomes of a cell in relation to number, size, and type. |
| LOCUS | A particular place along the length of a certain chromosome where a given gene is located. |
| MEIOSIS I | The first division of a two-stage process of cell division in sexually reproducing organisms that results in cells with half the chromosome number of the original cell. |
| MEIOSIS II | The second division of a two-stage process of cell division in sexually reproducing organisms that results in cells with half the chromosome number of the original cell. |
| SEX CHROMOSOMES | One of the pair of chromosomes responsible for determining the sex of an individual |
| SOMATIC CELL | Any cell in a multicellular organism except a sperm or egg cell. |
| SYNAPSIS | The pairing of replicated homologous chromosomes during prophase I of meiosis. |
| TETRAD | A paired set of homologous chromosomes, each composed of two sister chromatids. Tetrads form during prophase I of meiosis |
| ZYGOTE | The diploid product of the union of haploid gametes in conception; a fertilized egg. |
