  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-Dominance Incomplete 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
