Genetics

Why are punnett squares used?

• to know phenotypes

• for fun

• To organize your data

• to predict the possible genotypes of offspring

easily seen characteristics are called

• genetics

• observable traits

• DNA

• chromosomes

When offspring is the same as the parent

• self pollination

• pistil

• true breeding plant

• cross pollination

Why did Mendel use cross pollination in his experiments?

• to speed up self pollination

• to control which plants pollinated other plants

• to make sure dominant factors were always produced.
