What is an advantage of sexual reproduction?

• Only needs one parent
• Happens very quickly
• Offspring are exact copies of parent

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -

• makes its own food

• is unicellular

• live in a marine habitat

• reproduces asexually

When comparing the offspring of sexually and asexually reproducing organisms, we would expect the offspring of the sexually reproducing organism to -

• show genetic variation and be different

• show no genetic variation and be identical

• be simpler overall

Reproduction that combines genetic material of two organisms

• Sexual Reproduction

• Asexual Reproduction

• Fertilization

• Budding

What is one disadvantage of sexual reproduction?

• Only one parent needed

• Off spring are exact copies of parents

• Happens very quickly

• Needs two parents, must find a mate

What is a disadvantage of asexual reproduction?

• no genetic differences, they all have the same weaknesses

• can increase populations rapidly
