4. What was the name of the scientist who was the ‘father of genetics’?

5. What was the name of the scientist who was the ‘father of genetics’? MENDEL

6. What is the difference between dominant and recessive genes?

7. What is the difference between dominant and recessive genes? Dominant genes mask recessive genes. Dominant capital letter. Recessive lower case letter.

8. State at least 2 similarities between mitosis and meiosis.

9. State at least 2 similarities between mitosis and meiosis. Both begin with diploid cells. Both come after interphase. Both are examples of cell division. Both go through PMAT at least once.

10. State at least 2 differences between mitosis and meiosis.

11. State at least 2 differences between mitosis and meiosis. Mitosis makes 2 cells while meiosis makes 4. Mitosis cells are genetically identical while meiosis cells are genetically unique. Mitosis cells are diploid while meiosis cells are haploid.

12. During what process does the law of segregation take place and define the law of segregation?

13. During what process does the law of segregation take place and define the law of segregation? Prophase I in meiosis – process is crossing-over.

14. What does the law of independent assortment state?

15. What does the law of independent assortment state? How one chromosome moves during anaphase does not affect the movement of the other chromosomes.

16. Each of several alternative forms of a gene is called a(n) ______.

17. Each of several alternative forms of a gene is called a(n) ALLELE.

18. What is the genotypic ratio for the monohybrid cross below?

19. 1 TT: 2 Tt: 1 tt

20. Brown eyes dominates over blue eyes. If your sister is homozygous for brown eye color, what is your sister’s genotype? Use the letter E for eye color.

21. Brown eyes dominates over blue eyes. If your sister is homozygous for brown eye color, what is your sister’s genotype? Use the letter E for eye color. EE

22. Albinism is a recessive trait. If you are an albino, what is your genotype? Use the letter A in this problem.

23. Albinism is a recessive trait. If you are an albino, what is your genotype? Use the letter A in this problem. aa

24. If curly hair is dominant to straight hair, then what genotype must both parents have in order to have kids with a 50% of having curly hair and with a 50% chance of having straight hair? Use the letter T for type of hair. Complete a punnett square.

25. If curly hair is dominant to straight hair, then what genotype must both parents have in order to have kids with a 50% of having curly hair and with a 50% chance of having straight hair? Use the letter T for type of hair. Complete a punnett square. Parents have to be Tt and tt. – heterozygous and homozygous recessive.

26. In some radishes, red color is dominant over purple color. If two heterozygous parents are crossed, and if 200 offspring are produced from their seeds, how many offspring out of 200 should have the purple color? Use the letter R for radish color. A. What is the genotypic ratio of the offspring? B. What is the phenotypic ratio?

27. In some radishes, red color is dominant over purple color. If two heterozygous parents are crossed, and if 200 offspring are produced from their seeds, how many offspring out of 200 should have the purple color? Use the letter R for radish color. 50 will be purple. A. What is the genotypic ratio of the offspring? 1 RR: 2 Rr: 1 rr B. What is the phenotypic ratio? 3 red: 1 purple

29. In horses, black is dominant over brown. If a purebred dominant is crossed with a hybrid, what percent of the offspring produced will be hybrid? Use the letter B for horse color. Complete a punnett square.

30. In horses, black is dominant over brown. If a purebred dominant is crossed with a hybrid, what percent of the offspring produced will be hybrid? Use the letter B for horse color. Complete a punnett square. 50% will be hybrid (Bb)

31. Genetic make-up of an organism is a(n) _______.

32. Genetic make-up of an organism is a(n) GENOTYPE.

33. How are probability and genetics related?

34. How are probability and genetics related? A punnett square is only the probable genotypes of offspring, not the exact outcome.
