      –When 2 factors are considered and both parents are heterozygous for both, it is called a Dihybrid Cross –Remember, ONE copy of each gene is passed on to each gamete • •A cross between two individuals that are heterozygous for 2 traits will result in a 9:3:3:1 ratio of phenotypes: –9 Purple flower/Green pod –3 Purple flower/Yellow pod

      In humans, blood type is a result of multiple alleles: IA, IB, and iO. A few simple rules of blood type genetics are that xAI Ois dominant over i , xBI is dominant over iO, and x BIAI are codominant. Two parents who are heterozygous for type A blood and have sickle cell trait have children. Answer the following questions. a.

      Squares are one method for visually demonstrating the probability of offspring genotypes and offspring phenotypes. Example 1: (Monohybrid Cross) For humans, brown eyes are dominant (B) over blue eyes (b). A heterozygous brown-eyed man marries a heterozygous brown-eyed female. What are the possible genotypes and phenotypes of the offspring? Key:

      parents were heterozygous), and the second should be against the 1:1:1:1 model (to see if one parent was heterozygous, and the other was homozygous recessive). Compare your observed results to the expected results for each hypothesis and conduct the chi-square test. Show your calculations on your datasheet.
