Organisms that reproduce sexually have specialized cells called gametes (sex cells). Gametes are the result of a type of cell division called meiosis. Diploid and haploid. Almost all human cells are . How would you describe yourself? . Make a list of 5 characteristics…. Essential Questions. How are inherited traits different from learned behaviors?. Vocabulary to Know:. Inherited trait. Offspring. Reduction Division. Mike Clark, M.D.. Meiosis. Meiosis is nicknamed reduction division. It is a process where a cell divides (division) but reduces the genetic material to ½ (reduction) . This type of cell division occurs in the gametes (sex cells). Chapter 13. Vocabulary. heredity. variation. gene. gamete. somatic cell. asexual . vs. sexual reproduction. autosomes. sex chromosomes. allele. dominant . vs. recessive. diploid . vs. haploid. parental generation. Chapter 10. Overview of Meiosis. 10.1. Overview of Meiosis. Meiosis. - type of nuclear division that reduces the chromosome number from the diploid number to the haploid number.. Gametes. - reproductive cells. Alleles segregate during meiosis allowing new combinations to be formed by the fusion of gametes. . Understandings:. One diploid nucleus divides by meiosis to produce four haploid nuclei. . The halving of the chromosome number allows a sexual life cycle with fusion of gametes. . Mistakes in Meiosis. Many genetic disorders can be traced back to . errors in formation of the gametes . in meiosis. Could occur as the result of:. Mistakes in . separation of the chromosomes . during division. Image from about.com . meiosis_metaphase_1.jpg. . Mutations. (changes in an organism’s DNA) are the . original. . source of . all. genetic variation. Mutations create different versions of genes called . Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:. Differentiate between the process of mitosis and meiosis. Demonstrate the movement of chromosomes throughout meiosis. Analyze how meiosis leads to genetic variation.  . October 29, 2012. The J.

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. 1. MEIOSIS AND SEXUAL LIFE . CYCLES. Heredity. = Continuity of biological traits from one generation to the . next. Variation. = Inherited differences among individuals of the same . species. Genetics. Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the
