Lesson 1 Meiosis Review

What are the products of meiosis I?

• 4 haploid cells

• 2 diploid cells

• 4 somatic cells

• 2 haploid cells

Which of these is true of the products of Meiosis II?

• 4 haploid cells are produced

• 2 haploid cells are produced

• 4 diploid cells are produced

• 2 diploid cells are produced

In what way is Prophase I unique from Prophase II and prophase in mitosis?

• The cytoplasm has already divided

• The cell is still carrying out normal functions

• Homologous chromosomes pair up and exchange genetic information (crossing over)

• The chromosomes randomly bond to each other

Which phase of meiosis is most similar to metaphase in mitosis?

• Metaphase I

• Metaphase II

• Anaphase

• Synthesis

Why do human cells have 23 pairs of chromosomes?

• One chromosome from each pair comes from the mom and dad

• Each chromosome gets copied, so it has a pair of them

• To ensure that offspring will be identical to parents

Why do gametes only have half a set of chromosomes (haploid)?

• So the embryos is smaller

• To ensure the correct amount of chromosomes in the cell

• Less is better than more

• So genetic variation can occur easier

What are the products of meiosis?

• Offspring

• Somatic cells

• Germ cells

• Gametes

What is the correct order of the four phases of meiosis I and meiosis II?

• Metaphase, Anaphase, Telophase, Prophase

• Anaphase, Telophase, Prophase, Metaphase

• Prophase, Anaphase, Metaphase, Telophase

• Prophase, Metaphase, Anaphase, Telophase

What is uncoiled, stringy DNA called?

• Chromosomes

• Chromatin

• RNA

• Nucleotides

What happens before Prophase I, but not before Prophase II?

• DNA Replication

• Translation

• DNA condenses

• Spindle apparatus appears
