Happens in almost all cells (Somatic cells). 1 parent cell. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. .

Answer the following questions on the back of your review sheet.. Meiosis and Sexual Reproduction Chapter 6 Sexual Reproduction Sexual Reproduction – reproduction that requires two parents and produces offspring that are genetically different from each other and from either parent. a single . DNA molecule complexed with histone . proteins. DNA is organized within the nucleus as chromosomes. Each chromosome is comprised of subunits called nucleosomes: DNA + proteins. Chromosome numbering/naming. Haploid. Chromosome. Chromatid. Chromatin. Crossing Over. Tetrad. Gene –A segment of genetic information on a chromosome. Codes for a specific . characteristic. Allele – A specific form of a gene. Meiosis is the. . type of . cell division by which . germ cells . (eggs and sperm) . are produced. . One parent cell produces . four . daughter cells. . Daughter cells have half the number of chromosomes found in the parent cell. Cell division / Asexual reproduction.
