Why are all eggs produced by the same woman slightly different genetically?

• Due to crossover and recombination

• Due to mitosis

• Due to duplication of chromosomes

• Due to the presence of polar bodies

What happens during metaphase I of meiosis?

• Chromosomes line up in a single row

• Chromosomes are pulled apart into separate single chromosomes

• Crossover and recombination occur

• Centrosomes head to their corners of the cell

What is the purpose of the polar bodies in egg production?

• To provide nutrients to the embryo

• To carry genetic information

• To regulate cell division

• To produce endosperm in plants

What is the final result of meiosis in males?

• Four sperm cells with different genetic information

• One egg and three polar bodies

• Two identical cells with 46 chromosomes

• Two sperm cells with the same genetic information
