BIOLOGY Tuesday 31 Jan 2017 Entry Task What is the phenotype for the pea? • Round & Green What are the possible genotypes for seed shape & seed color of the pea? • Seed shape: RR & Rr • Seed color: yy p. 310 Agenda Housekeeping Section 11.1 (The Work of Gregor Mendel) Amoeba Sisters Video Chpt 11 Workbook Housekeeping Chpt 11 exam scheduled for Friday, 10 Feb. • Kahoot review on Thursday, 9 Feb. Gregor Mendel Genes & Alleles: Dominant & Recessive Alleles: p. 310 Gregor Mendel Segregation: p. 311-312 Video Monohybrids and the Punnett Square Guinea Pigs (6:27): • Link: https://www.youtube.com/watch?v=i-0rSv6oxSY Chpt 11 Workbook Complete the workbook during the course of this unit. • Workbook will be collected on the day of the exam. • Chpt 11 workbook can be located @ http://www.steilacoom.k12.wa.us/Page/5839 BIOLOGY Wednesday 1 Feb 2017 Entry Task What are the possible allele combinations for the parents of a short homozygous recessive (tt) pea plant? • Both parents are homozygous recessive (tt) • Both parents are heterozygous (Tt) • One parent is homozygous recessive (tt) & the other is heterozygous (Tt). Agenda Housekeeping Section 11.2 (Applying Mendel’s Principles) Punnett Square Practice Worksheet Chpt 11 Workbook Housekeeping Chpt 11 exam scheduled for Friday, 10 Feb. • Kahoot review on Thursday, 9 Feb. Mendel’s Principles Segregation used to predict outcomes. • Allele segregation just as random as a coin flip. F2 generation contains different combinations of alleles. • Homozygous vs Heterozygous p. 314 Mendel’s Principles Genotype vs Phenotype: • Genotype = genetic makeup • Phenotype = physical traits (observable) p. 314 Punnett Square Punnett Squares: • Simple diagrams that use mathematical probabilities to help predict the genotype & phenotype combinations in genetic crosses. p. 315 Independent Assortment Principle of Independent Assortment: • Genes for different traits can segregate independently during the formation of gametes. p. 317 Punnett Square Practice Complete the “Punnett Square Practice Worksheet”. • Worksheet will be checked Friday, 3 Feb., @ the beginning of class. • “Punnett Square Practice Worksheet” can be located @ http://www.steilacoom.k12.wa.us/Page/5839 Chpt 11 Workbook Complete the workbook during the course of this unit. • Workbook will be collected on the day of the exam. • Chpt 11 workbook can be located @ http://www.steilacoom.k12.wa.us/Page/5839 BIOLOGY Thursday 2 Feb 2017 Entry Task If a heterozygous brown dog is crossed with a homozygous white dog, what are the possible offspring genotypes & phenotypes? (draw a punnett square to solve) • Genotypes = Bb (2) & bb (2) • Phenotypes = brown (2) & white (2) Agenda Housekeeping Section 11.2 (Applying Mendel’s Principles) Punnett Square Practice Worksheet Chpt 11 Workbook Housekeeping Chpt 11 exam scheduled for Friday, 10 Feb. • Kahoot review on Thursday, 9 Feb. Independent Assortment How many different allele combinations in the gametes of parent pea plant with the genotype of GgAa? • Four = GA, Ga, gA, ga p. 317 Independent Assortment Complete the Punnett square with parents having the allele combinations for pod shape & plant height of SSTt & ssTt. ST St St sT SsTT SsTt SsTT Sstt Sstt SsTT SsTT st Sstt SsTt Sstt p. 317 Punnett Square Practice Complete the “Punnett Square Practice Worksheet”. • Worksheet will be checked Friday, 3 Feb., @ the beginning of class. • “Punnett Square Practice Worksheet” can be located @ http://www.steilacoom.k12.wa.us/Page/5839 Chpt 11 Workbook Complete the workbook during the course of this unit. • Workbook will be collected on the day of the exam. • Chpt 11 workbook can be located @ http://www.steilacoom.k12.wa.us/Page/5839 BIOLOGY Friday 3 Feb 2017 Entry Task Explain how traits could disappear and then reappear generations later. Agenda Housekeeping Amoeba Sisters Video Section 11.3 (Other Patterns of Inheretance) Chpt 11 Workbook Housekeeping Chpt 11 exam scheduled for Friday, 10 Feb. • Kahoot review on Thursday, 9 Feb. • Study guide handed out on Monday, 6 Feb. Video Punnett Squares and a Dihybrid Cross (8:31): • Link: https://www.youtube.com/watch?v=qIGXTJLrLf8 Other Patterns Beyond Dominant & Recessive: Exceptions to Mendel’s work. • Genetics is more complicated. • Majority of genes have more than two alleles. • Some traits controlled by more than one gene. p. 319-320 Other Patterns Beyond Dominant & Recessive: Think, Pair, & Share • Designate in your groups who is reading which sections. - Incomplete Dominance (p. 319) - Codominance (p.319) - Multiple Alleles (p. 320) - Polygenic Traits (p.320) • Silent (no talking) read & make notes for 5 min. • One person will share for 1 min., then the group will have 1 min. to ask questions. Next person will share, etc. p. 319-320 Other Patterns Incomplete Dominance: • Some alleles are neither dominant nor recessive. • Not completely dominant. • Heterozygous phenotype lies between homozygous phenotype. p. 319 Other Patterns Codominance: • Phenotype produced by both alleles clearly expressed. • Colors appear separately. p. 319 Other Patterns Multiple Alleles: • Genes with more than two alleles. • Two alleles is the exception not the rule. • Ex. Humane gene for blood type. p. 320 Other Patterns Polygenic Traits: • Traits produced by the interaction of several genes. • Polygenic = “many genes”. • Show a wide range of phenotypes. • Ex. Humane skin color controlled by 4 different genes. p. 320 Genes & the Environment Environmental conditions can affect gene expression & influence genetically determined traits. p. 321.
