inheritance patterns and variation in
organisms.
Answer 2 – 10

• Cross
Question 2 - 40
• ___________ are distinguishing characteristics
that are inherited, such as eye color, leaf

• Traits
Question 2 - 50
• The following components summarize what?

expressed when two different alleles are
present. A ______________ allele is only
expressed when two copies are present.
