Meiosis Flashcards
About meiosis
What is meiosis?
Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.
True or False: Meiosis results in two diploid cells.
False: Meiosis results in four haploid cells.
What are the two main stages of meiosis?
The two main stages of meiosis are meiosis I and meiosis II.
Fill in the blank: During meiosis I, homologous chromosomes are separated during __________.
anaphase I.
What is the purpose of meiosis?
The purpose of meiosis is to produce gametes for sexual reproduction.
Multiple choice: Which of the following occurs during prophase I?
Homologous chromosomes undergo crossing over.
What is crossing over?
Crossing over is the exchange of genetic material between homologous chromosomes during prophase I.
True or False: Meiosis II is similar to mitosis.
True: Meiosis II is similar to mitosis as it separates sister chromatids.
What is the result of meiosis I?
The result of meiosis I is two haploid cells, each with half the original chromosome number.
Fill in the blank: The cells produced at the end of meiosis are called __________.
gametes.
What is the significance of genetic variation in meiosis?
Genetic variation is significant as it contributes to the diversity of traits in a population.
Multiple choice: How many times does DNA replication occur before meiosis?
Once, during interphase before meiosis I.
What happens during metaphase I?
Homologous chromosomes align at the equatorial plane of the cell.
True or False: Each gamete contains a complete set of chromosomes.
False: Each gamete contains half the number of chromosomes.
What is the final outcome of meiosis?
The final outcome of meiosis is four genetically unique haploid cells.
