3. A genetic disorder characterized by uncontrolled bleeding.
What is hemophilia?

4. This genetic disorder is shown in the karyotype above.
What is Turner’s Syndrome?

5. A dominant autosomal disorder that is a form of dwarfism.
What is Achondroplasia?

6. What is Tay-Sachs disease?
Genetic disorder found in European Jews that causes blindness, mental retardation, and muscle weakness.
What is Tay-Sachs disease?

7. Duchenne Muscular Dystrophy has this pattern of inheritance.
What is sex-linked recessive?

8. What is incomplete dominance?
A cross of a white rabbit with a black rabbit produces offspring with grey fur. What type of inheritance pattern does this show?
What is incomplete dominance?

9. What is multifactoral inheritance?
This type of inheritance is shown by a woman who has a predisposition for lung cancer and begins smoking at 15 years old – as a result, she ends up getting lung cancer at age 50.
What is multifactoral inheritance?

10. This inheritance happens when a brown fur squirrel is mated with a grey furred squirrel, and the offspring show patches of both grey and brown fur.
What is codominance?

11. What is 1 red : 2 roan : 1 white?
The phenotype ratio of offspring in horses when two roans (a blend of red and white colors that result when a red horse mates with a white horse) are crossed.
What is
1 red : 2 roan : 1 white?

12. A man with two normal-sighted parents inherits his color blindness from this person.
Who is his mother?

13. The probability that a gamete will contain the genes “Ry” if the diploid cells contain the “Rryy” gene combinations.
What is 50% (½)?

14. The probability that a woman whose first baby was a boy will give birth to a second baby boy.
What is 50%?

15. The likelihood that a child with type O blood type has a mother with type A blood and a father with type AB blood.
What is 0%?

16. In Four O’Clocks, the gene for red flowers (R) is incompletely dominant to the gene for white flowers (W). A cross between a white flower and a red flower would result in this percentage of pink flowers.
What is 100%?

17. The probability that a man with normal color vision and a woman who had a colorblind father and a normal mother will have a boy.
What is 50% (½)?

18. An organized picture of a person’s chromosomes in which chromosomes are arranged and numbered by size, from largest to smallest.
What is a karyotype?

19. Most sex-linked genes are found on this chromosome.
What is the X chromosome?

20. How you can tell if a trait or disorder in a pedigree is sex-linked.
What is if it affects males more than females?

21. What is nondisjunction?
The failure of homologous chromosomes to separate from one another during meiosis.
What is nondisjunction?

22. Cells that contain one allele per trait.
What are haploid cells (gametes)?

23. The monomers for proteins.
What are amino acids?

24. The organelles in which the electron transport chain takes place.
What are mitochondria?

25. The sequence of nucleotides on the mRNA if the sequence on the DNA is as follows: ATGCAT
What is UACGUA?

26. The phase of meiosis in which crossing over takes place.
What is Prophase I?

27. An organism that makes its own food.
What is an autotroph?
