Question # 7 • What are the 3 checkpoints of the cell cycle?
Round 1 Answers • cytokinesis • Centromere • Spindle • Metaphase • G1, S, G2 • Produces more cells for growth, repair and differentiation • centioles • S phase (synthesis)
Round 2 • Volume • Diploid- two full sets of chromosomes, somatic cells, Haploid- only one set of chromosomes, sex cells or gametes • anaphase 4. Volume of the cube 5. Prophase and metaphase 6. 46 7. G1, G2, and Mitosis
Question #1 A son gets the Y chromosome from which parent?
Question #2 The actual appearance or feature that is shown for a trait is called the ________________
Question #3 If a coin is tossed 3 times what is the probability of getting tails all three times?
Question #4 This Mendelian Principle states that one of the alleles always overpowers the other allele.
Question #5 Which trait disappeared in the F1 generation but then reappeared in the F2 generation?
Question #6 Which of Mendel’s principles states that each parent can only pass on one of the two alleles they have for a trait.
Question #7 The actual alleles an organism possesses for a trait is called the _______________
Question #8 If you rolled a pair of dice what is the chance of getting double 6s?
Question #9 Someone who shows the dominant phenotype could have which possible genotypes?
Question #10 Which of Mendel’s principles explains why a tall plant with purple flowers and a short plant with white flowers could produce an offspring that is tall with white flowers?
Question #11 A specific genetic characteristic that can be inherited
Question #12 Mendel’s term for organisms that were the offspring of two different purebreds
Question #13 If the parental genotype for two traits is AaBb what gamete combinations are possible?

Round 3 Answers: 1. The father 2. phenotype 3. ½ x ½ x ½ = 1/8 4. Principle of dominance 5. recessive 6. segregation 7. genotype 8. 1/6 x 1/6 = 1/36 9. Homozygous dominant or heterozygous 10. Independent assortment 11. Trait 12. hybrid 13. AB, Ab, aB, ab 14. Punnet square 15. 1 AA, 2 Aa, 1 aa
Question #1 1 pair of the human chromosomes are the sex chromsomes. What are the other 22 pairs of human chromosomes called?
Question #2 A picture of all the human chromosomes properly paired up is called _____________
Question #3 Why are traits carried on the X chromosome more common in males?
Question #4 Which type of trait typically forms a bell-curve when graphed?
Question #5 If one parent has blood type AB and the other parent has blood type O what are the possible blood types for their child?
Question #6 A diagram that shows inheritance patterns with in a family is called a ______________.
Question #7 When homologous pairs exchange parts of their chromosome it is called ______________
Question #8 If a female has a gene for an X-linked trait but does not show the trait herself she is said to be a _____________
Question #9 Neither allele truly dominates and the heterozygous shows a mix of both traits
Question #10 Because an individual can inherit an A, B or O allele from each parent this type of trait is called ________________
Question #11 Colorblindness and hemophilia are both examples of this type of trait.
Question #12 In this type of trait neither allele overpowers the other and the heterozygous shows BOTH phenotypes
Question #13 What is the probabilty that these parents will have a child with O blood type? Parents: AO x AB
