1. Alternative Patterns of Inheritance Warm-Up Objective Powerpoint Packet/book work – what you don’t finish is HW Exit Ticket Name and describe an example of genetic recombination.

2. Objective Students will demonstrate understanding of the different types of inheritance (co- dominance, sex-linked, incomplete dominance) by independently completing a worksheet. By the end of class today, you will be able to identify and describe codominance, incomplete dominance, and sex-linked inheritance

3. Co-DominanceIncomplete Dominance

4. Co-Dominance There are multiple dominant alleles that are both expressed in the phenotype. If there are multiple Dominant alleles, how would you write that? Aa wouldn’t be enough.

5. Incomplete Dominance Neither allele is dominant, so the heterozygote creates a combined phenotype. What’s the difference between incomplete dominance and co- dominance?

6. Sex-linked When an allele is on a sex-chromosome. Hemophilia is x-linked recessive. What does this mean? Why are men more likely to get hemophilia?

7. Exit Ticket Which type of inheritance is demonstrated by the picture? How can you tell. 3 sentence limit
