For mitosis to take place: A. the parent cell must divide its DNA in half so each daughter cell gets only the genes needed to carry out its functions. In this way, differentiation occurs. B. the parent cell must reproduce its DNA during telophase C. the parent cell must first be fertilized D. the parent cell must replicate its entire genome prior to mitosis E. crossover must be delayed until the second cell divisionarrow_forward

If a gamete of an unknown animal species has 44 chromosomes, how many of each of the following structures will be present? 5. chromatids at anaphase I 6. chromatids at telophase II 7. centromeres after telophase I 8. centromeres after prophase II 9. chromosomes after anaphase II 10. chromosomes at metaphase Iarrow_forwardFor the following events, specify whether they occur during mitosis, meiosis I, or meiosis II:A. Separation of conjoined chromatids within a pair of sisterchromatidsB. Pairing of homologous chromosomesC. Alignment of chromatids along the metaphase plateD. Attachment of sister chromatids to both polesarrow_forwardFor below problem, consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. Each pair contains a maternal and a paternal member (e.g., Am and Ap). Using these designations, demonstrate your understanding of mitosis and meiosis by drawing chromatid combinations as requested. Be sure to indicate when chromatids are paired as a result of replication and/or synapsis. You may wish to use a large piece of brown manila wrapping paper or a cut-up paper grocery bag for this project and to work in partnership with another student. We recommend cooperative learning as an efficacious way to develop the skills you will need for solving the problems presented throughout this text. Question: Assume that each gamete resulting from Problem 29 fuses, in fertilization, with a normal haploid gamete. What combinations will result? What percentage of zygotes will be diploid, containing one paternal and one maternal member of each chromosome pair?arrow_forward

- Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is eliminated, resulting in a diploid offspring.The process that produces the sperm and egg, and the process the offspring use to grow into adults are, respectively, Select one: a. Process to produce sperm and egg Process used for growth of the offspring Mitosis Cytokinesis b. Process to produce sperm and egg Process used for growth of the offspring Mitosis Meiosis c. Process to produce sperm and egg Process used for growth of the offspring Meiosis Cytokinesis d. Process to produce sperm and egg Process used for growth of the offspring Meiosis Mitosisarrow_forwardWhich of the following occur during anaphase II of meiosis? Select one: a. The APC adds phosphates to motor proteins causing them to rebuild the nuclear envelope. b. Homologous chromosomes of the tetrad separate and move to opposite poles of the newly dividing cell. c. DNA de-condenses. d. Non-identical (due to recombination) sister chromatids are split, attach to motor proteins, and are moved to separate polesarrow_forwardCan be more than one answer: Select all of the following that are true of MEIOSIS but not of MITOSIS. a) cell division occurs during cytokinesis b) results in two identical daughter cells c) halves the number of chromosomes in a cell d) spindle fibers contract during anaphase e) tetrads line up on metaphase platearrow_forward
