• 6

Which best describes the process shown?

• segregation of sister chromatids

• condensation and segregation of the alleles

• crossing-over which alleles are exchanged

What is one advantage of sexual reproduction?

• offspring are identical to parents
• offspring are resistant to viruses
• offspring are born live, rather than from eggs
