meiosis

The result of meiosis is:

• two diploid cells
• two haploid cells
• four diploid cells
• four haploid cells

During meiosis I, what happens? 

• Sister chromatids are split
• Homologous chromosomes are split
• Four cells are created
• None of the other choices are correct

Crossing over is important because....

• It prevents mutations from entering the gametes. 
• It allows for even distribution of chromosomes in the gametes.
• It allows for more genetic diversity of gametes.
• It allows for genetic uniformity of gametes. 

You inherited...

• most of your chromosomes from your mother
• most of your chromosomes from your father
• a random number of chromosomes from each parent
• half your chromosomes from your mother and half from your father.
