Which traits are multi-allelic (controlled by more than one allele)?
Is trait expression purely genetic or can environment be involved?
Heterozygous, homozygous, dominant and recessive mean:___
Genes, alleles, and traits are________
What happened when Mendel crossed purebred tall and short
plants? Who was Mendel anyway?
6. Be able to draw, analyze, and interpret Punnett squares.
7. What is cloning?
8. Compare and contrast selective breeding and genetic engineering?
9. Compare and contrast mitosis and meiosis. How many chromosomes
do human somatic (“normal” cells) have? How many do human
gametes have?
10. Compare and contrast codominance and incomplete dominance?
Give examples.
11. What is the chromosome theory of inheritance?
12. What is a genome?
13. What combinations of chromosomes results in a male? Female?
14. What is a pedigree? Know what the circles and squares represent.
Know what a carrier is. Be able to draw/interpret one.
15. What causes genetic disorders? Are all mutations harmful?
16. What are hemophilia, cystic fibrosis, Kleinfelters’ syndrome,
Turner’s syndrome, and Down syndrome?
17. What causes colorblindness? Are males or females more likely to
have it?
18. What is a Karyotype and why do we use them?
19. What is amniocentesis?
20. What does purebred mean? What is a hybrid?
21. If you flip a coin, what is the probability of it landing heads up?
What is the probability of it landing heads up if you flip it again?
What about a third time? Why?
22. If you have the alleles IAIB, what is your blood type? Can your
child be type O? Explain.
23. If empty-head syndrome (EHS) is sex-linked on the X
chromosome, what would the Punnett square for a cross between
an affected male and normal female look like? What is the
probability of them having a kid with EHS?
Pedigree Case Study
Jim and Cindi
 Have three kids: 1 boy and 2 girls
 Girl #1 appears healthy
 Girl #2 and Boy have empty-head
syndrome (a recessive trait ee)
 Cindi’s dad has EHS but Cindi does not
 Jim and his parents don’t have
symptoms
 Jim’s grandfather on his mom’s side had
EHS
