Paull BIO 212 Problem Set #5 (15 pts) Due on March 3/4 Handout #5: Meiosis/Monohybrid cross 1. Imagine a diploid cell with 4 different chromosomes, A, B, C and D. There are 2 different types of homologs for each chromosome, A and a, B and b, C and c, D and d. a. (1 pt) If the diploid cell undergoes meiosis, how many possible genotypes could there be after meiosis II (considering independent segregation only, not crossovers) ? 16. b. (3 pts) List the genotypes of all these cells from part a : ABCD , abcd, ABCd , abcD, ABcD, abCd, AbCD, aBcd, aBCd, AbcD, aBcD, AbCd, aBCD, Abcd, abCD, ABcd c. (1 pt) If the A,B, C, and D homologs came from Mom, and a, b, c, and d came from Dad, is it possible that a gamete created during meiosis could contain DNA that originated from only one parent? What is the probability of this occurrence? 1 in 8, or 12.5% e. (1 pts) If the original diploid cell had two copies of the same chromosome A (instead of having two different forms, A and a), how many different genotypes could there be after meiosis I?

    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.
