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?

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 - 20

• What are the genotypes of the F1 generation of the following cross?

• Rr x Rr

Squares – 20

• ¼ RR• ½ Rr• ¼ rr

• 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.
