The Hopi, Zuni, and some other Southwest American Indians have a relatively high frequency of albinism resulting from homozygosity for a autosomal recessive allele, a . A normally pigmented man and a normally pigmented woman, each of whom has one albino parent, have two children. What is the probability that at least one of the two children is albino? ANSWER: The probability that a child is not albino is ¾. The probability that neither child is albino is (3/4)(3/4)=9/16. The probability that at least one child is albino is 1-(9/16)=7/16. 22. From the F2 generation of a cross between mouse genotypes AA × aa , one male progeny of genotype A named LAZY was chosen and mated with an aa female. All of the progeny in the resulting litter were A . From this result, can you reject the null hypothesis that LAZY’s genotype is A a , and why? Consider two situations when the litter size is 3 and 9, respectively.

    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.
