Question 1 of 2

A checkpoint, not a test

Explain the returning white flowers

A few sentences is enough. Explain the reason in your own words.

Mendel’s F1 flowers were purple, but white flowers reappeared in F2. Explain how the white-flower allele could remain in F1 and then be expressed in F2.

Separate an allele’s presence from the trait that is visible.

Question 2 of 2

A checkpoint, not a test

One allele in each gamete

A few sentences is enough. Explain the reason in your own words.

A parent has two different alleles for a gene. Explain what the law of segregation predicts for its gametes and how fertilization restores an allele pair in an offspring.

Follow the pair as gametes form and then join.
