How many daughter cells are produced from meiosis ?

• 10
• 6
• 4
• 2

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids

• condensation and segregation of alleles

• mutationin which the DNA content of the gene is altered

• crossing over or recombination in which alleles are exchanged

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells
