The chromosomes that pair up during meiosis are called __________ chromosomes.  

• homozygous 
• autosomal
• homologous
• genes

Why do we need meiosis?

• To double the number of chromosomes going into sex cells so that offspring have double the number of chromosomes as parent.
• To halve the number of chromosomes going into sex cells so that offspring have the same number of chromosomes as the parent.
• To triple the number of chromosomes going into sex cells, so that offspring have triple the number of chromosomes as parent.
• To not change the number of chromosomes going into sex cells, so that offspring have the same number of chromosomes as a parent's gamete.
