18 Questions
What is the main goal of meiosis?
Reduce chromosome number
What is the main difference between Meiosis I and Meiosis II?
Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids.
During which phase of meiosis does crossing-over occur?
Prophase I
Which stage of Meiosis II is correctly matched with its description?
Anaphase II - sister chromatids separate.
What is the result of Meiosis I?
Production of haploid daughter cells
What happens during crossing over in Meiosis?
Sister chromatids intertwine and swap pieces of chromosome.
Which process leads to the production of gametes with different genetic makeups?
Meiosis I
What is the term used for the pairing of homologous chromosomes during meiosis?
Synapsis
Which stage of Meiosis I involves the complete formation of the spindle apparatus?
Metaphase I
When do sister chromatids separate in meiosis?
During Anaphase II
How does meiosis contribute to genetic recombination?
By crossing over and creating new combinations of traits
What is the outcome of meiosis in terms of chromosome number compared to the parent cell?
Diploid to haploid
During which phase of the cell cycle does DNA replication take place?
S phase
Which type of cell division involves the reduction of the number of chromosomes in daughter cells?
Meiosis
What is the main difference between Mitosis and Meiosis?
Mitosis results in genetically identical daughter cells, Meiosis results in genetically diverse daughter cells.
What is the significance of Meiosis in the production of gametes?
To reduce the number of chromosomes by half
During which phase of Meiosis does crossing-over occur?
Prophase I
What is the result of Meiosis II?
Formation of haploid daughter cells
Test your knowledge on the differences between meiosis and mitosis, including the replication of DNA in the S phase, crossing over during Prophase 1, and the separation of sister chromatids in Meiosis 2. Understand how meiosis evolved after mitosis and why it is convenient to use the machinery of mitosis.
