   Sexual reproduction requires more energy and resources; however, most complex organisms reproduce sexually. What advantage does sexual reproduction give these organisms?

• It is a fast process.

• It results in more offspring.

•   It increases genetic diversity.

•   It requires time to find a mate.

The sperm cells of a dog have 38 chromosomes. How many chromosomes will be in the muscle cells of a dog?

• 19

• 38

• 76

• 152

The main difference between mitosis and meiosis is that…

 

• DNA replicates during mitosis, but not during meiosis.

•   Mitosis makes genetically identical copies, meiosis does not.

• Sister chromatids separate in mitosis, but not during meiosis.

• Mitosis increases chromosome number in each cell while meiosis decreases it.
