Question

1. Why were Gregor Mendel's studies important to our understanding of genetics?

2. What do P, F1 and F2 refer to in Gregor Mendel's studies?

3. What ratio of the traits did he find in the F2 generation (when he crossed heterozygous parents)?

4. Define these terms: dominant, recessive.

5. Define allele.

6. Define these terms: genotype, phenotype.

7. Define these terms: heterozygous, homozygous.

8. Understand how you determine the phenotypic ratio and the genotypic ratio of possible offspring using a Punnett Square.

9. Practice doing Punnett Squares for monohybrid crosses. The link to practice problems is in the lesson for this chapter on p. 6.

10. What is the difference between a monohybrid and a dihybrid cross?.

12. For blood type, we see codominance. Which two blood types are codominant? Which blood type is recessive?

13. Practice Punnett squares for blood type. Watch the video and do the practice problems. There will be a question on this on the test.

14. How is sex determined in humans?

15. Why do recessive defects on the X chromosome show up in boys, but usually not in girls?

16. What are some examples of X-linked traits?
