What did Gregor Mendel use to discover the principles that rule heredity?

• Pea plants

• Pigeons

• Pear trees

• Photosynthesis

What happened to the green trait in Mendel's pea plants?

• It disappeared

• The pea plants produced 50% less green seeds

• It was hidden by the dominant yellow gene

• Nothing happened to the green gene

What did Mendel call the two kinds of traits exhibited by the pea plants (one coming from the father, one from the mother)?

• Genesis

• Elective traits

• Alleles

• Quadrants

What do we call the table used to determine the traits

• Punnett square

• Venn diagram

• Golden ratio

• Fibonacci sequence

• genes

• DNA

• traits
