Mr. Niemis' Flipped Lessons - Di-Hybrid Punnett Squares (Older)

What is the primary purpose of a di-hybrid cross in genetics?

• To study a single trait in offspring.

• To determine the sex of offspring.

• To predict the inheritance of two different traits at once.

• To observe changes in a species over time.

When setting up a di-hybrid Punnett square, which method helps determine all possible combinations of alleles from one parent?

• The Mendelian method

• The FOIL method

• The segregation method

• The dominance method

In a di-hybrid cross involving guinea pigs where black hair (B) is dominant to white (b) and long hair (L) is dominant to short (l), if both parents have the genotype BbLl, what is the expected phenotypic ratio for black long-haired offspring?

• 1 out of 16

• 3 out of 16

• 9 out of 16

• 16 out of 16

Besides using a large 4x4 Punnett square, what is another way to find the probability of inheriting two traits from two parents?

• Only observing the offspring directly.

• Creating two separate Punnett squares for each trait and multiplying their probabilities.

• Guessing based on the parents' appearance.

• Using a monohybrid cross for each parent.
