2. Mendel’s rule stating that and organism possesses 2 genes for every trait. What is the rule of Unit Factors? 1 - $100

3. 1 - $200 Organisms have 2 alleles for every trait. Their gametes have only 1. Which of Mendel’s principles best illustrates this fact? • What is the Law of Segregation?

4. 1 - $300 • List 3 reasons Mendel’s choice to work with pea plants was a good one. • Can self pollinate, Traits with 2 distinct phenotypes, Small & Reproduce quickly

5. 1 - $400 • How are the principles of segregation and independent assortment related? • Allele pairs segregate from one another at gamete production. This occurs for each gene, independently of other genes.

6. 1 - $500 • Diploid cells of the fruit fly Drosophila melanogaster have 8 chromosomes. How many chromosomes would you find in the following fruit fly cells: • Sperm cell • Muscle cell • Brain cell • Sperm: 4 (gamete) • Muscle: 8 • Brain: 8

7. 2 - $100 • What is the predicted phenotypic ration for the cross below? Rr x Rr, where R = round seeds and r = wrinkled seeds • 3:1

8. 2 - $200 • In pea plants, tall is the dominant height allele. Design a test cross to determine the genotype of a tall pea plant. What results would you expect if the parent were homozygous? Heterozygous? • What is cross the tall plant with a homozygous recessive (short) plant. All tall offspring  parent was homozygous tall ½ tall offspring  parent was heterozygous tall.

9. 2 - $300 • List all possible gametes that could be made by a parent with the genotype AaBBCc • Gametes (1of each gene): ABC, ABc, aBC, aBc

10. 2 - $400 • A cross between a tall and a short pea plant results in the following offspring: 52 tall, 55 short What are the most likely genotypes of the parent plants? Explain using a Punnett square. T t A homozygous short plant (recessive) crossed with a heterozygous tall plant. t t

11. 2 - $500 • Set up a Punnett square to show a cross between the following parents: TtPPYY x TTPpYy TPY TPy TpY Tpy TPY tPY

12. 3 - $100 • What is a polygenic trait? Give an example. • A trait controlled by more than 1 gene. Examples: height, skin color, eye color

13. 3 - $200 • Differentiate between the following terms: Gene, allele, chromosome. • Alleles are distinct forms of a gene. Genes are segments of chromosomes that code for proteins (traits). Chromosomes are long strands of DNA, containing many genes.

14. 3 - $300 • If a heterozygous individual has a trait that is not shared with either parent, that trait is referred to as … • Incompletely Dominant

15. 3 - $400 • A mother with type O blood and a father with AB could produce these offspring. • What are A and B?

16. 3 - $500 • What is the predicted phenotypic ratio of offspring that would result from the following cross: AaBb x AaBb *Note: A and B are dominant over a and b respectively. • 9:3:3:1

17. 4 - $100 Answer any 4 of the following: In which US state could you visit • 1> the Space Needle? • 2> the Valley Forge National Historic Park? • 3> the Mark Twain House? • 4> the Okefenokee Swamp? • 5> the Lincoln Log Cabin? • 6> the Yellowstone National Park? • 7> the Portage Glacier? • 8> Cripple Creek? • 9> the U.S. Naval Academy Annapolis? • 1> Washington 2> Pennsylvania 3> Connecticut 4> Georgia 5> Indiana 6> Wyoming 7>Alaska 8> Colorado 9> Maryland

18. 4 - $200 • In Laborador retrievers, coat color is controlled by two genes. Black coat color (B) is dominant to brown coat color (b). However, dogs that are homozygous recessive at another unlinked gene (e) are yellow. What is the name for this type of inheritance? • Epistasis

19. 4 - $300 • Because the sickle-cell gene affects more than one phenotypic trait in affected individuals, it is an example of _____________. • Pleiotropy

20. 4 - $400 • If a female fruit fly homozygous for red eyes is crossed with a white eyed male, what percentage of the offspring would have white eyes? • If two of the F1 offspring from question 4 were crossed, what percentage of the F2 generation would have white eyes? • F1: 100% Red • F2: 25% White eyes. (No females, ½ of males)

21. 4 - $500 • A certain species of moth may have antennae that are feathery or non-feathery. Those with non-feathery antennae usually have white eyes. Antennae type and color are each controlled by a single pair of genes. Suggest a valid conclusion that can be drawn regarding these genes. • The 2 genes are linked – found on the same chromosome
