Types of Crosses - 10
• Between parents that differ in traits for a single character
Types of Crosses– 10
• Monohybrid
Types of Crosses - 20
• Between parents that differ in traits for two characters
Types of Crosses– 20
• Dihybrid cross
Types of Crosses - 30

• Bonus 50- Why do we do this cross?
Types of Crosses– 50
• Test cross
Mendel - 10
• What plant did Mendel work with?
Mendel – 10
• Peas
Mendel - 20

Mendel - 30
• What are the three different generation names and what do they result from?
Mendel – 30
• P
• F1
• F2
Mendel - 40
• What was Mendel’s profession?
• Bonus 10: What is his first name?
Mendel – 40
• Austrian Monk• Bonus: Gregor
Mendel - 50
• What was Mendel’s first law?
• Bonus 20: Explain
Mendel– 50
• The law of segregation
• Each individual can have two alleles that encode different traits for one character; these alleles separate from one another when gametes are formed (this occurs during Anaphase I of meiosis).
Squares - 10
• What are the genotypes of the F1 generation of a monohybrid cross of the following?
• RRxrr
Squares – 10
• All Rr
Squares - 20
• What are the genotypes of the F1 generation of the following cross?
• Rr x Rr
Squares – 20
• ¼ RR• ½ Rr• ¼ rr
Squares - 30
• In a test cross, the results are as follows. What is the genotype of the unknown parent?
• ½ dominant phenotype• ½ recessive phenotype
Squares – 30
• Heterozygous
Squares - 40
• Why is it that some traits “skip” a generation?
• Bonus 40: Draw punnent squares to illustrate your answer.
Squares – 40
• RR x rr = all dominant phenotype• Rr x Rr = ¼ recessive phenotype
Squares - 50
• An initial cross is made between a true breeding tall plant and a true breeding dwarf plant.
• What are the genotypes and phenotypes of the F1 generation?
• The F1 is selfed.• What are the genotypes and phenotypes of
the F2 generation?
Squares – 50
• F1– all Tt– all Tall
• F2– ¼ TT, ½ Tt, ¼ tt– ¾ Tall, ¼ Dwarf
