B. The first two words are s eparated by a colon. These two words are related to each other. Analyze this relationship in order to fill in the ANALYZE missing word that will complete the second pair. 1. mitosis: somatic cells meiosis: 2. gap 1: G1 to S checkpoint mitosis: 3. diploid: 46 chromosomes haploid: mitosis: nucleus cytokinesis: 5. plants: cell plate animals: 6. interphase: chromatin 7. condensed: chromosome uncoiled: 4. mitosis: 8. animals and plants: life cycle cell: 9. chromosomes: homologous pairs chromatids: 10. haploid: one set diploid:

A. 1. Division of the cell nucleus, results in two daughter nuclei, each have the same number of chromosomes as the parent nucleus. 2. One two identical halves of a duplicated chromosome. 3. Fusion of haploid (n) gametes; results in the formation of a diploid (2)n zygote. 4. The breaking and rejoining of homologous (non sister) chromatids during early meiotic prophase I, resulting in an exchange of genetic material. 5. The diploid (2n) cell that results from the union of haploid (n) gametes in sexual reproduction. 6. The condition of having one set of chromosomes per nucleus. 7. The complex of DNA, proteins and some RNA that makes up eukaryotic chromosomes. 8. Structures in the cell nucleus, composed of chromatin and containing the genes. 9. An X-shaped site in a tetrad marking the location where homologous chromatids previously underwent crossing over. 10. A sex cell; in plants and animals, an egg or sperm. 11. Type of reproduction in which two gametes (usually, but not necessarily,…
