Which of Mendel's laws can be see on this monohybrid punnett square?

• Segregation

• Independent Assortment

• Incomplete dominance

• Dominance

Dihybrid punnet squares are used to demonstrate the law of independent assortment. What does this punnett square tell us about the traits for color and shape in pea plants?

• The traits for color and shape are determined by a single gene, not two separate genes.
• The traits for color and shape do not assort independently, leading to a 1:1:1:1 ratio.
• The traits for color and shape assort independently, resulting in a 9:3:3:1 phenotypic ratio.
• The traits for color and shape are linked, resulting in a 3:1 phenotypic ratio.

What is the phenotypic ratio for the cross shown by the dihybrid punnett square?

• 3:1:1:9

• 1:1:1:1

• 9:3:3:1
• 9:1:2:5

In this dihybrid cross, Round (R) is dominant to wrinkled (r). Yellow (Y) is dominant to green (y). How many offspring should be yellow and wrinkled?

• 9

• 2
• 1
• 3

How can independent assortment be related to variation?

• Independent assortment only occurs in asexual reproduction, not in sexual reproduction.
• Independent assortment decreases genetic variation by limiting allele combinations.
• Independent assortment has no effect on genetic variation in gametes.
• Independent assortment increases genetic variation by producing different combinations of alleles in gametes.

In pea plants, yellow is dominant to green. Mr. Mendel wants to see how traits are passed down. He crosses a true-breeding yellow plant with a true-breeding green plant. If one of the offspring self-fertilized, what would the genotypic ratio for the F2 generation be?

• 1:2:1
• 2:1:0
• 1:1:1
• 3:1:0
