Human Influence on Inheritance Test Review

Gregor Mendel experimented with pea plants in the mid-1800s. He helped lay the foundation for our understanding of artificial selection. In one experiment that studied seed colors, he observed that a yellow pea crossed with a green pea always produced a yellow pea. When he then bred those yellow peas together, he observed that there were some green peas, at a ratio of one green pea to every three yellow peas. What conclusion about the peas is best supported by the data from Mendel’s experiment?

• The trait of green peas is recessive.

• The trait of yellow peas is recessive.

• Traits that show up in offspring are always present in parents.

• Later generations of peas would have a higher ratio of green peas.
