43. Mitosis produces two identical daughter cells while meiosis produces 4 identical gametes. 

28. Human blood type is a codominant trait, with three alleles for red blood cell surface carbohydrates. A couple has 4 children, all with different blood types: A, B, AB, and O. What are the blood types of the parents?

31. In mice, black fur (B) is dominant to white fur, pink tails (P) are dominant to white tails, and big ears (E) are dominant to small ears.  If a female mouse heterozygous for all three traits mates with a male mouse who has white fur, a white tail, and small ears… what is the probability that their offspring will have the same phenotype as the mother?

36. When DNA is transcribed, and mRNA is translated, the code is read three bases at a time. If the original DNA bases read    A  T  C, what would the corresponding mRNA codon be?

16. Which of the following statements regarding enzymes is true?

1. When crossing an organism that is homozygous recessive for a single trait with a heterozygote, what is the chance of producing an offspring with the homozygous recessive phenotype?  

31. Denatured enzymes can be reused as long as their substrate is small enough to fit in the active site.
