Activity: Dihybrid Crosses with other Inheritance Patterns Dihybrid Crosses with Incomplete Dominance In a certain breed of cat the alleles for tail length and coat color are as follows Cat Tail Length Cat Coat Color L=Long N=No Tail L+N = Short B= Black b= White Perform a cross between a heterozygous black long tailed cat with a white short tailed cat. Provide a complete genetic analysis. BbLL x bbLN Gametes: (BL, bL)x (bL, bN) Offspring: 2 x 2 = 4 offspring possibilities BL bL bL BbLL bbLL bN BbLN bbLN Genotypic Results: 25% BbLL 25% bbLL 25% BbLN 25% bbLN Phenotypic Results: 25% Black with long tail 25% White with long tail 25% Black with short tail 25% White with short tail What are the chances of producing a cat with no tail? 0% Chance

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
