  3. Monday, 3-31-14 Bell work…10 min Complete Posters…30 min Begin Presentations…10 min. Ticket out…5 min. HOMEWORK: Read & Note 14.1 Objective: I will demonstrate understanding of mutations through poster presentations.

  4. TUESDAY

  5. BIO I 1,2,5,7 Period 4-1-14 Bell work:Preview Chapter 14 by answering questions 1-9 on page 415. Objective: I will demonstrate understanding of human genetics through presentations and discussion. HOMEWORK: Read & Note 14.2.

  6. Tuesday, 4-1-14 Bell work…5 min Presentations…30 min Quick Lab…15 min Ticket out…5 min. HOMEWORK: Read & Note 14.2. Objective:I will demonstrate understanding of human genetics through presentations and discussion.

  7. Notes 14.1 • Karyotype • Shows the complete diploid set of chromosomes grouped together in pairs in decreasing size. • Genome – full set of genetic information Sex Chromosome – 2 of the 46 Chromosomes determine sex Autosome – the other 44 chromosomes

  8. Many human traits follow a pattern of simple dominance – Ff, FF, ff • Sex Chromosomes – determine an individual’s sex. Females have 2 XX’s Males an X and a Y. • Female – XX Male – XY • A sex-linked gene is a gene located on a sex chromosome. • The information gained from pedigree analysis makes it possible to determine the nature of genes and alleles associated with inherited human traits.

  9. WEDNESDAY

  10. BIO I 1,2,5,7 Period 4-2-14 Bell work: Complete “Analyzing Data” pg. 400 questions 1-3. Objective: I will demonstrate understanding of genetic disorders and inheritance patterns. HOMEWORK: Read & Note 15.1.

  11. Wednesday, 4-2-14 Bellwork…5 min. Notes 14.2…10 min. Pedigree Activity…35 min Ticket Out…5 min HOMEWORK: Read & Note 15.1. Objective: I will demonstrate understanding of genetic disorders and inheritance patterns.

  12. Notes 14.2 • Small changes in DNA molecules can affect human traits. • Individual Gene Disorders • Base change from Guanine to Adenine produced dry ear wax instead of wet earwax. (Substitution) • Deletion of 3 bases in a gene causes cystic fibrosis. (deletion) • The codon CAG replicats over and over more than 40 times creates Huntington’s Disease (Duplication) • Genetic Advantages – Some diseases make humans immune to other infections even if they are just a carrier.

  13. Those with sickle cell anemia are immune to Malaria. • Those with Cystic Fibrosis are immune to typhoid fever. Chromosomal Disorders nondisjunction – (not coming apart) chromosomes fail to separate creating three copies – trisomy • Down Syndrome Nondisjunction of the X and Y chromosome • Turner’s syndrome – Females • Klinefelter’s Syndrome – Males

  14. THURSDAY

  15. BIO I 1,2,5,7 Period 4-3-14 Bell work: Answer “Key Questions” on pg 418. Turn in Bell work Books. Objective: I will understand the purpose of selective breeding through discussion and review. HOMEWORK: Complete worksheets to review for quiz on Monday.

  16. Thursday, Bell work 4-3-14 Bell work…5 min Read & Notes 15.1…30 min. Review worksheets…15 min. Ticket out…5 min. HOMEWORK: Complete worksheets to review for quiz on Monday. Objective: I will understand the purpose of selective breeding through discussion and review.

  17. Notes15.1 Selective Breeding – allowing only desired characteristics to produce in the next generation. Hybridization – crossing dissimilar individuals to bring together the best of both organisms. • often hardier than either parent Inbreeding – continued breeding of individuals with similar characteristics. • pedigree dogs

  18. Increase genetic variation by introducing mutations. • Biotechnology – when scientists manipulate the genetic makeup of organisms through technological processes, inventions, or method. • Bacterial Mutations – using radiation or chemicals • Polyploidy – drugs that increase the number of chromosomes – producing larger stronger plants.
