HSC Biology Module 5 Reproduction Reproductive success The ability to produce fertile offspring that survive to reproductive maturity and produce offspring of their own. Biological fitness the measure of an individual's reproductive success. It is calculated as the average contribution to the gene pool made by a certain genotype within a population and the relative likelihood that these alleles will be represented in future generation. Sexual reproduction It involves the meet...

Two types of cell division in eukaryotes - Answer-Mitosis, Meiosis Meiosis produces - Answer-gametes (sex) Mitosis produces - Answer-somatic cells (non-stem, non-sex) Cell division in prokaryotes is called - Answer-Binary fission In binary fission, the parent cell... - Answer-...divides to create *clonal* daughter cells (identical to each other + parent cell) Mitosis is - Answer-the division of the nucleus cytokinesis is - Answer-the division of the cytosol + other organelles 3 Functions...

Mitosis • the duplication and division of the nucleus • results in clones with *no* variation or adaptation • takes place in somatic cells (non-sex cells) • starts with one cell and creates 2 identical daughter cells • replicated chromosomes are evenly divided so that each daughter cell receives a complete set (46 chromosomes) • *can occur by itself*, but usually involves cytokinesis • not synonymous with cellular division • single-celled prokaryotes and single celled euk...

BIOS-251: Exam 2 Review with Verified Solutions Cell division in which the nucleus divides into nuclei containing the same number of chromosomes Mitosis The resting phase of mitosis. Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases Interphase Cells that have left the cycle and cease dividing for a long time (or permanently) G Zero (G0) Phase The first gap, or growth phase, of the cell cycle, consisting of the portion of inte...

Brooks Biological Principles Exam 3 with Certified Solutions Mitosis duplication of cells through asexual reproduction Mitosis is not synonymous with cell division What organisms go through mitosis? single-celled prokaryotes and single-celled eukaryotes Where does mitosis take place? somatic cells Product of mitosis 2 identical diploid daughter cells Purpose of Mitosis growth, repair, and asexual reproduction Cell Division process by which a parent cell duplicates its gen...

Cell Cycle An ordered sequence of events in the life of a cell Mitosis A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei. Cytokinesis The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II. Cell Division The reproduct...
