1. The Father of Heredity

2. Gregor Mendel

3. Synonym for “Trait”

4. Allele

5. A structure located in the nucleus where DNA is stored

6. Chromosome

7. What is the passing of genetic material from one generation to the next generation called?

8. Heredity

9. Physical appearance that reflects your genotype

10. phenotype

11. This shows possible phenotypes and genotypes of what an offspring could look like or what genes they can inherit

12. Punnett Square

13. This is a picture of chromosomes arranged from biggest to smallest. It shows an organism’s sex and possible disorders

14. Karyotype

15. “Genes” the make up of the combination of traits you inherit from your parents (EX. AA, Bb, cc, Dd)

16. Genotype

17. 2 copies of the same allele: BB, bb

18. Homozygous: BB – dominant bb - recessive

19. 2 words that describe these types of alleles: Bb Tt Ss

20. Heterozygous OR Hybrid

21. in order for this recessive trait to be seen, the offspring must have two…

22. of the same alleles - Homozygous recessive (little letters)

23. The actual genetic information for a particular trait is called:

24. gene

25. A person who studies heredity is called:

26. A geneticist

27. The gene or allele that is most likely expressed or seen in an offspring – only one is needed to show trait

28. Dominant: TT Tt

29. Physical appearance

30. Phenotype – what an organism looks like

31. 4 facts about Gregor Mendel

32. 1- he was a monk 2 – he was a gardener 3- he grew pea plants 4 – he was Austrian 5 – he studied heredity 6 – lived around 1850

33. Genes that make up the combination of traits you inherit from your parents (EX. AA, Bb, cc, Dd) are called:

34. Genotype – gene combinations by letters

35. Give the genotype and phenotype ratios of this Punnett square (T = tall, t = short):

36. genotype: 1 homozygous dominant (TT) 25% 2 heterozygous or hybrid (Tt) 50% 1 homozygous recessive (tt) 25% 1:2:1

37. In garden snakes, yellow is dominant (Y) over green, and round is dominant (R) over flat. Cross a hybrid male in color who is flat, with a green female who is heterozygous shape. What are the ratios for the offsprings?

38. Yyrr (male) “x” yyRr (female) Results: Yellow + round – 4/16, 1/4 Yellow + flat – 4/16, 1/4 Green and round – 4/16, 1/4 Green and flat – 4/16, 1/4 RATIO: 1:1:1:1
