You will need to study for this test!! Please review your past quizzes to help you as well! I encourage
you to study your notes in addition to this paper, your crossword, and past quizzes! Especially review
your Meiosis Quiz! It's been a while since we've seen that concept! Also, review the STUDY STACKS
for this!! They are on my website!! Good luck!
1.) Define dominant and recessive.
2.) What is incomplete dominance? Give an example.
3.) What is codominance? Give an example.
4.) What are the ratios Mendel got in the F2 gen.? Explain these ratios using a punnett square.
5.) What is the difference between phenotype and genotype?
6.) What makes sex cells different from regular body cells?
7.) Define and give examples of each genotype:
Heterozygous –
Homozygous Dominant –
Homozygous Recessive –
8.) Do the punnett square for this cross: Tt x Tt
T = tall t = short
What is the phenotypic ratio? ________ What is the genotypic ratio? _________
What is the probability of having a tall pea plant? ______ out of ______ or ________%
What is the probability of a heterozygous genotype? _______ out of ______ or _______%
What is the probability of a homozygous recessive genotype? _______ out of ______ or _______%
9.) What approximate ratio of traits did Mendel calculate in his F2 gen.? How did he get this ratio?
10.) In Mendel's experiment, what is the result of the cross between the 2 P gen. plants? Explain why he
got this result.
11.) Define sex-linked traits. Give an example.
12.) Define polygenic traits. Give an example.
13.) Define multiple alleles. Give an example of codominance in multiple allelic traits.
