3.4 Genetic traits result in observed inheritance patterns. 3.5 Patterns of inheritance can be explained through Mendel’s laws of segregation and independent assortment. 3.6 Probabilities for genotype and phenotype combinations in monohybrid crosses can be modeled using a Punnett Square.

 *two page notebook format* Page 65 Do Now:  1) List traits that are widely different from person to person. (Reminder: Eye color is a trait, and brown eyes is one version or expression of that trait)  2) How might these traits be inherited, so that more than two patterns of inheritance are possible?  3) Are these patterns of inheritance Mendelian? Tuesday, Jan 6, 2015 P 66  Topic: Genetics  Objectives, language objectives :  Describe different types of allele interactions.  Describe polygenic traits and the effect of environmental factors on phenotype.  Language Objectives: Use the terms gene, allele, homozygous, heterozygous, genotype, phenotype, dominant, incomplete dominance, codominance, polygenic trait, Punnett Square, probability, and recessive orally and in writing. (same language through Genetics unit – today’s focus in large type)

How might these traits be inherited, so that more than two patterns of inheritance are possible? (that means, there are more than brown or blue eyes possible)

 Before we go further… Khan Academy video “Co-Dominance and Incomplete Dominance” Use note taking organizer as we watch and learn. Insert this page in your notes, or add definitions.

 7.2 Formative Assessment  Choose and answer 2 questions from numbers 1-6 on page 191, on left side of notebook. For extra credit, do #6.  SUMMARIZE what you learned today in 3-5 sentences on bottom of right side.  Homework:  Study Guide 7.2  Complete lab write-up if not done in class.
