Practice 4.4

Independent assortment contributes to genetic diversity. When does independent assortment occur?

• Prophase I
• Metaphase I
• Anaphase I
• Prophase II

After meiosis is complete, the new cells:

• are all identical
• are all different
• are half identical and half different
• are all stretched out

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. 

Unique gametes are produced by which of the following? 

• Independent assortment during meiosis I.
• Independent assortment during meiosis II.
• Selective assortment during meiosis I.
• Selective assortment during meiosis II.

During meiosis I, what happens? 

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

The transmission of characteristics from parents to offspring

• Heredity

• Genetics

• Trait

• Allele
