No notes for slide
  • Point out that the homework page is in the hand-out.Also point out the additional references in the hand-out (BrainPOP and talking glossary links).Point out that I will be cruising throughout the class during the lab if anyone has any questions.
  • Discuss warm-up which leads into our 5-Alive
  • We discussed this a few days ago
  • Yesterday we discussed meiosis
  • So we know that although both mitosis and meiosis are both forms of cell division, they are very different
  • Meiosis produces daughter cells with half of the number of chromosomes as the parent cell….it only has ½ of the genetic info as the parent
  • Notice that the parent cell begins with 46 chromosomes (2n) and the daughter cells (ovum and sperm) each contain 23 chromosomes (n)
  • A male gamete (sperm) and a female gamete (ovum) unite (fertilization) to form a zygote.The male gamete contributes 23 chromosomes (n) and the female gamete contributes 23 chromosomes (n) so the zygote contains 46 chromosomes (2n).
  • The sorting and recombination of genes during fertilization provides for genetic variation among individuals.It provides for variation in the offspring.This is where we pick up to begin today’s discussion. We want to know what happens to that zygote, what its options are in terms of traits, when it is, basically, randomly getting half of its info from mom and half from dad.
  • Point out the link to this video in the hand-out.
  • Point out that these definitions are in the hand-out. Also point out the link in the hand-out to the talking glossary of terms.
  • Students will be assigned to their groups prior to instruction of new content.
  • I will use guided instruction and modeling to demonstrate the content of today’s lesson
  • The format of the homework page is exactly the same as the classwork page.

    1. 1. Today’s schedule Pick-up daily notes Complete the warm-up: Mitosis and meiosis are both forms of cell division. Please list and/or describe 1 similarity and 2 differences between them. *The warm-up will be displayed on the smartboard as students enter. Discuss the warm-up. PowerPoint begins at this point: 5-Alive Recap: Lively 5 minute review/recap of previous lesson *if this goes over 5 min that is fine Introduce today’s topic and objectives (will be written in hand-out as well as on whiteboard) BrainPOP video Vocabulary review Group assignments (by me, pre-determined) Classwork page: complete together Bean-otype lab activity: complete in small groups Discuss lab as class Homework will be independent practice on genotypes, phenotypes, & Punnett squares Exit ticket Also turn in lab pages upon exitingschedule
    2. 2. MSDE (2012):INDICATOR3.3.2 The student will illustrate and explain how expressed traits are passed from parent to offspring.Assessment limits: phenotypes (expression of inherited characteristics) dominant and recessive traits sex-linked traits (X-linked only; recessive phenotypes are more often expressed in the male) genotypes (represented by heterozygous and homozygous pairs of alleles) Punnett square (use to predict and/or interpret the results of a genetic cross; translate genotypes into phenotypes - monohybrid only) pedigree (use to interpret patterns of inheritance within a family)common core
    3. 3.  Mitosis and meiosis are both forms of cells division. Pleaselist/describe1 similarity & 2 differencesbetween them.warm-Up
    4. 4. cell division mitosis and meiosis 5-alive recap
    5. 5.  Mitosis: Parent cell (n) creates identical daughter cells (n) Mitosis occurs all over Mitosis creates all types of cellsmitosis
    6. 6.  Meiosis: Parent cell (2n) creates unique daughter cells (n) Meiosis only occurs in gonads Meiosis only creates sex cellsmeiosis

    12. 12. Objectives By the end of today’s lesson, students will be able to discuss Mendelian genetics & heredity using scientific vocabulary with 85% accuracy by practicing it in small groups. By the end of today’s lesson students will be able to explain the relationship between meiosis & heredity with 85% accuracy by viewing a PowerPoint presentation. By the end of today’s lesson students will understand, with 85% accuracy, that the sorting and recombination of genes that occurs during fertilization leads to genetic variation among offspring by completing a lab activity.objectives

    14. 14. Genotype: The 2 alleles inherited for a particular gene (the code) Phenotype: Observable traits (outward expression of the genotype) Allele: One of two or more versions of a gene Trait: A specific characteristic of an organism which can be determined by genes or the environment, or more commonly by interactions between them Gene : The basic physical unit of inheritance. Genes are passed from parents to offspring and contain the information needed to specify traits; found on chromosomes.crucial vocabulary
    15. 15. Dominant vs. Recessive: Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.Homozygous: An individual inherits the Heterozygous: An individual inheritssame alleles for a particular gene from different alleles for a particular gene both parents. from each parent. Pedigree: A genetic representation of a Punnett square: A diagram used to family tree that diagrams the determine possible phenotypes. inheritance of a trait or disease though several generations Inherited trait: One that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are notstrictly determined by genes, but rather are influenced by both genes and environmenta few more terms…
