Questions and Answers

What does the Principle of Independent Assortment explain about genetic traits?

Traits only segregate during fertilization.

All traits are inherited together.

Different traits are inherited independently from each other. (correct)

Traits can only be inherited from one parent.

What was the outcome when Mendel crossed true-breeding round, yellow peas with wrinkled, green peas?

The offspring showed only one trait of the parents.

The offspring displayed a mix of traits.

The offspring were all wrinkled and green.

All offspring were round and yellow. (correct)

Which of the following best describes Mendel's F2 generation offspring?

They displayed only one trait from the parents.

They were all true-breeding.

They reproduced without segregation.

They had combinations of alleles not present in the F1 generation. (correct)

Study Notes

Probability & Punnett Squares

Independent Assortment answers Mendel's questions about inheritance.
Mendel crossed true-breeding plants with different traits (e.g., round yellow peas vs. wrinkled green peas).
The offspring (F₁) all showed one trait from each parent (e.g., all round yellow).
The F₂ generation showed new combinations of traits not seen in the initial parents, demonstrating Independent Assortment.
Genes for different traits segregate independently during gamete formation, resulting in genetic variation.
This is because different traits are on different chromosomes.
