Test your understanding of mendelian genetics with 5 practice questions.

Practice Questions

Question 1

Which of the following scenarios best illustrates the application of Mendel's Law of Independent Assortment?

Question 2

In a dihybrid cross, if two parents with genotypes $AABb$ and $AaBb$ are crossed, what is the probability of obtaining offspring with the genotype $AABb$?

Question 3

If a plant with genotype $RrYy$ (where $R$=red, $r$=white, $Y$=yellow, $y$=green) is self-pollinated, what is the expected proportion of offspring that will have red flowers and green seeds?

Question 4

A geneticist performs a test cross on a pea plant with a dominant phenotype for height (tall). The offspring produced include both tall and short pea plants. What was the genotype of the tall parent plant?

Question 5

In a dihybrid cross, if the genes for two traits are located on the same chromosome and are very close together, which of Mendel's laws is most likely to be violated?
