Multiple Choice

A researcher is trying to determine how Mendel’s laws apply to heredity in pea plants. She crosses a round, yellow seed pea plant with a wrinkled, green seed pea plant to produce the F1 generation. Two offspring of the F1 generation were crossed to produce the F2 generation. The data for the F1 and F2 generations were recorded in the table. Which question, if investigated, would BEST lead to a connection between the data and Mendel’s law of segregation?

• Why is there increased genetic variation in the F1 generation compared to the F2 generation?

• Can plants produce offspring that have different phenotypes than either parent?

• Why are there no wrinkled plants in the F1 generation?

• Why did all the F1 offspring end up round and yellow?

an organism has two copies of a gene (one from mom and one from dad) that are separated when gametes form​

Law of Segregation

P= (round + yellow)​ x (wrinkled green)
