Trivia Friday Your team consists of the individuals sitting with you at your table. First, come up with a team name. Fill out a card indicating your team name and all group members. A Question will be read and will remain on the board for 30 seconds. Copy it down! Write your answer on a piece of paper and turn it into the scorekeeper. The team with the most points will win a prize!

Question 1 Red is incompletely dominant over white. What is the phenotypic ratio when two heterozygous flowers are crossed?

Answer 1 1 red: 0 pink: 0 white

Question 2 In order to have children with 4 different blood types, what must the parent’s blood types be?

Answer 2 I A i I B i

Question 3 When a heterozygous female is crossed with a color-blind male, what are the chances of having a color-blind child?

Answer 3 50%

Question 4 Blood groups are a classic example of what type of inheritance (not codominance)? You may use your book.

Answer 4 Multiple Alleles

Question 5 If both alleles are always expressed, they are said to be: incompletely dominant dominant and recessive co dominant polygenic

Answer 5 Codominant

Question 6 A normal man marries a woman with hemophilia. They have a son. What are the chances that he has hemophilia?

Answer 6 100%

Question 7 What is a test cross? You may use your book. Show a test cross with a heterozygote (using a Punnett Square).

Answer 7 Any cross with a homozygous recessive individual… used to find out the genotype of the other parent.

Question 8 Mr. Jones has blood type A and Mrs. Jones has blood type AB. What is the probability that they will have a child with blood type A if both of Mr. Jones’ parents were AB? Show the Punnett Square.

Question 9 Name a fatal disease that is dominant. How is it possible for it to be passed from generation to generation if it is deadly?

Question 10 Tall pea plants are dominant over short pea plants. What is the phenotypic ratio of the offspring of a purebred tall plant and a purebred short plant?

Question 11 What are all the possible gametes for an individual who is TtBb

Question 12 A normal woman marries a man who is color blind. They have a colorblind daughter and a normal daughter. Give the genotypes for both the mom and the normal daughter.

Question 13 Name five patterns of inheritance. A sixth will earn you a bonus point.

Question 14 A man has type B blood. His mother had type O blood. What are the possible genotypes for his father?

Question 15 Tall pea plants (T) are dominant over short pea plants (t). When crossing two heterozygous plants, what percentage of the offspring will likely be Tall.
