Question 13Points:10 out of 10Genes A and B do NOT sort independently (because they are in the samelinkage group; assume recombination does not occur between these twogenes). An individual is AaBb and has the A and the b alleles on one copy ofthe chromosome and the a and the B alleles on the other chromosome. Howmany different gametes are produced?
34FeedbackCorrect. This individual will produce 2 different gametes, they are either Abor aB.Question 14Points:10 out of 10What would be the result of fertilization if egg and sperm were produced bymitosis rather than meiosis?
Question 15
Points:0 out of 10In peas purple is dominant to white for flower color. A purple flower iscrossed with a white flower. All the offspring (over 100 plants) producepurple flowers. What is the genotype of the purple flower?PpppPPEither PP or PpFeedbackIncorrect. This flower would be white.
Question 16Points:10 out of 10Red (R) flower color is incompletely dominant to white (r) flower color. Twopink flowers are crossed. What percentage of their offspring will be pink?
50%25%FeedbackCorrect. Pink flowers have aRr genotype. A cross of Rr x Rr results in 50%Rr (pink) offspring. The cross also produces 25% RR (red) and 35% rr(white).Question 17Points:10 out of 10A female produces gametes
