Meiosis and Gametogenesis

What is the major difference between sexual and asexual reproduction?

• Sexual reproduction does not require cell division.
• Asexual reproduction cannot occur in diploid species.
• Asexual reproduction cannot occur in eukaryotes.
• Asexual reproduction produces offspring identical to the parent.

What happens to the polar body?

• It eventually becomes an egg 
• It eventually becomes a sperm
  
• It becomes a diploid cell
  
• It is broken down and discarded

During which phase of meiosis does independent assortment occur?

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

How are meiosis and gametogenesis linked in plants?

• Meiosis produces haploid gametes directly.
  
• Meiosis produces haploid gametes that are then modified by the sporophyte to produce functional gametes.
• Meiosis produces a haploid cell that divides by mitosis to form a gametophyte, which then produces gametes by mitosis.
• They are not linked in any way.

Which meiotic division more closely resembles mitosis?

• Meiosis I
• Meiosis II
  
• Both resemble mitosis closely.
  
• Both have significant differences from mitosis.
  A replicated chromosome and a bivalent.

Meiosis results in _____

• 2 haploid daughter cells
• 4 diploid daughter cells
• 2 diploid daughter cells
• 4 haploid daughter cells
