Wednesday Quiz on 10/2 Entire unit Test on 10/8 Reminder! Wednesday Quiz on 10/2 Entire unit Test on 10/8

AGENDA Do Now! (5 mins) Go over the Punnet Squares (15 Mins) Discuss Dihybrid Cross (10 minutes) Video on Mendelian Genetics (10 Mins) Practice the Dihybrid Cross (20 mins) Closure (10 mins)

Do Now!!!

Dihybrid Cross Dihybrid crosses: Crosses that examine the inheritance of two different traits. 9 genotypes 4 phenotypes 9 : 3 : 3 : 1 ratio

Dihybrid Cross Parents have 2 different sets of alleles

Law of Independent Assortment Mendel’s 2nd Law Allele pairs separate independently of each other during gamete formation (meiosis) Different traits appear to be inherited separately.

Remember! Every time you see a Dihybrid Cross think about Law of Independent Assortment.
