Vocabulary Somatic Cell Gamete Homologous Chromosomes Diploid Cells 2n Haploid Cells n Normal body cell Sex cell sperm or egg Matching pairs of chromosomes Cells that have homologous chromosomes somatic cells. Chromosomes in Reproductive Cells? Introduction Sexual reproduction is a process that creates a new organism by combining the genetic material of two organisms. There are two main steps in sexual rep Chapter . 11. Genes and Development. Fig. 11.1. Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display.. Haploid sperm.

Sexual Life Cycles. modes of reproduction. diploid/haploid and meiosis. meiosis I and meiosis II phases. key differences between mitosis and meiosis. variation in position of meiosis in life cycles. why sex?. ch. : 7. Sexual or Asexual. Asexual – involves a single parent organism and produces off-spring or daughter cells that are clones. Sexual Reproduction – involves genetic contribution in the form of gametes from two sources. Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:.

Review of Mitosis. Mitosis is a form of . asexual reproduction. This means that it . only requires 1 organism . (ex. Skin cells dividing). For growth and repair in . somatic. (body) cells!. Results in 2 cells identical to the original (parent) cell. 10.2 – Meiosis Sexual Reproduction Function: creates gametes (sperm, egg, pollen) for sexual reproduction . Meiosis: Cell division for sexual reproduction. Males - testes Females - ovaries Sex Cells 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. Organisms that reproduce sexually are generally diploid: each cell contains two sets of chromosomes—a maternal chromosome set and a paternal chromosome set—one inherited from each parent. . .

Mitosis. produce cells with same information. identical daughter cells. exact copies. clones. same amount of DNA . same number of chromosomes. same genetic information. In asexual reproduction, a single individual gives rise to offspring that are identical to itself and . others [MITOSIS]. Bacteria reproduce asexually. Most plants and some simple animals can reproduce both asexually and .
