11. Mendel called the parental plants the _______ generation, which he used to
get the _________ generation, or first filial generation.
12. What did Mendel notice about the F1 generation compared to the P
generation?
13. To get the _________ generation, Mendel crossed two individuals from the
F1 generation.
14. A ______________ is a unit of heredity that determines traits.
15. The two contrasting forms of a gene are called _____________.
16. What is a dominant allele?
17. What is a recessive allele?
18. In rabbits, black fur is dominant to white fur.
A. What letter will you use to represent this trait?_____________
B. Write the letter combination representing the following genotypes, then
write the corresponding phenotypes:
Genotype:
Homozygous dominant:
Phenotype:
Heterozygous:
Homozygous recessive:
19. What is the difference between genotype and phenotype?

22. What is meiosis?
23. ________________ cells are regular body cells that are ______________,
meaning they have two sets of chromosomes.
24. Reproductive cells called __________________ are ________________,
meaning they have only one set of chromosomes.
25. Fertilization is the fusing of haploid gametes that forms a diploid cell called a
_________________.

chromosome number)
30. What is the difference between incomplete dominance and codominance?
Provide an example of each.
31. Human blood groups are an example of ________________________.
32. What are some traits that are controlled by polygenic inheritance (more than
one gene)?
