Flashcards on Meiosis
Click on the flashcard to see the answer
What is meiosis?
Meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell.
How does meiosis differ from mitosis?
Meiosis results in the formation of four non-identical daughter cells, while mitosis produces two identical daughter cells.
What are the two main stages of meiosis?
The two main stages of meiosis are meiosis I and meiosis II.
What is crossing over?
Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis.
What is the purpose of meiosis?
The purpose of meiosis is to produce genetically diverse gametes for sexual reproduction.
Which cells undergo meiosis?
Meiosis occurs in cells that give rise to gametes, such as sperm and egg cells.
What is the significance of independent assortment in meiosis?
Independent assortment allows for different combinations of genes to be present in gametes, leading to genetic variability.
What is the end result of meiosis?
The end result of meiosis is the formation of four haploid cells with unique genetic combinations.
What is the function of spindle fibers in meiosis?
Spindle fibers help separate the chromosomes during meiosis, ensuring each daughter cell receives the correct number of chromosomes.
When does genetic recombination occur in meiosis?
Genetic recombination occurs during meiosis I through the process of crossing over.
During which phase of meiosis does independent assortment occur?
Independent assortment occurs during metaphase I of meiosis.
