2. A phenotype that requires only one set of genetic instructions to be produced is known as this
What is dominant
Category

3. The ABO blood type system is an example of this, where two different alleles both produce proteins and get expressed independently
What is co-dominance?
Category

4. The two alleles for a gene are found on these two DNA molecules
What are homologous chromosomes?

5. This type of inheritance pattern (though relatively rare) would result in traits more likely to be expressed in females than males
What is X-linked dominant?

6. Daily Double! Explain incomplete dominance at a molecular level
What is heterozygotes produce fewer functional proteins so the phenotype is a blend?
Or heterozygotes produce both proteins which lead to a blended phenotype
Daily Double!

7. What the odds a two people with AB+- blood have a child with AB+- blood?
What is ½*1/2 = ¼ or 4/16=1/4 IA IB AB + - +- A+ B+ A- B-
AB+-

8. Two brown-eyed parents who are heterozygous in both genes mate
Two brown-eyed parents who are heterozygous in both genes mate. This is the odds their child is green eyed
What is 3/16

9. An individual with the genotype AaBbDdEeFF can produce how many unique gametes? (assume all genes on separate chromosomes)
What is 24 = 16

11. Two genes affect the color of fur of a particular animal
Two genes affect the color of fur of a particular animal. When two AaBb animals mate, 6/16 of them have gray fur. 1/16 have white fur while the rest have black fur. This is the most likely explanation for the presence of gray fur.
What is producing the dominant phenotype in only 1 gene leads to gray fur (in both= black, in neither=white)

12. This is the only disease we covered in which either parent must have the disease to pass it on
What is Huntington’s disease?

13. These two disorders are more common in males than females
What are color-blindness and hemophilia?

14. This disorder occurs when both parents pass on defective instructions for an enzyme in the brain
What is Tay-Sachs?

15. This is the reason sickle-cell anemia is so common in sub-Saharan African countries
What is sickle-cell trait provides resistance to malaria (heterozygotes are at an advantage)

16. Cystic Fibrosis victims have a dysfunctional this
What is CFTR protein or chloride ion channel protein?

17. The conversion of chromosomes from their unduplicated to duplicated (X) form occurs during this in both mitosis and meiosis
What is interphase?

18. Homologous chromosomes are separated in this stage
What is (anaphase I) of meiosis I

19. Daily Double! These are 3 differences between mitosis and meiosis
Which cells go through process (stem cells vs. germ cells
What cells are produced (somatic cells vs. gametes)
# of cell divisions (1,2)
# of daughter cells (2,4)
# of chromosomes in daughter cells (all, half)
Identical daughter cells vs. unique daughter cells
Function (growth vs. reproduction)
Daily Double!

20. A mosquito has 6 chromosomes in total
A mosquito has 6 chromosomes in total. How many genetically unique offspring can two mosquitoes produce?
64. Each can produce 8 unique gametes
PPP, PPM, PMP, PMM, MPP, MPM, MMP, MMM

21. The somatic cells of a koala have 16 chromosomes
The somatic cells of a koala have 16 chromosomes. Sketch a Koala cell at metaphase of mitosis, meiosis I and meiosis II

22. This term describes two molecules of DNA that code for the same genes, but may contain different alleles
What are homologous chromosomes

23. This type of inheritance can produce a wide range of phenotypes as opposed to either-or phenotypes
What is polygenic or multigene inheritance

24. This term describes how one gene affects the expression of another gene and is a major reason for human genetic complexity
What is epistasis

25. Identify 4 different inheritance patterns we have discussed
Complete dominance
Incomplete dominance
Co-dominance
X-linked
Polygenic
Epistatic

26. Genes are instructions for producing different proteins
Genes are instructions for producing different proteins. Different genes must code for different sequences of these.
What are amino acids?
