meosis Flashcards
What is the process by which a diploid cell divides to produce four haploid cells?
Meiosis
True or False: Meiosis involves two rounds of cell division.
True
During which phase of meiosis do homologous chromosomes pair up and exchange genetic material?
Prophase I
What is the term for the exchange of genetic material between homologous chromosomes during prophase I of meiosis?
Crossing over
True or False: Meiosis results in genetically identical daughter cells.
False
During which phase of meiosis do chromosomes line up at the equator of the cell?
Metaphase I
What is the name of the process in meiosis where homologous chromosomes separate and move to opposite poles of the cell?
Anaphase I
At the end of meiosis I, are the resulting cells haploid or diploid?
Haploid
Which phase of meiosis involves the separation of sister chromatids?
Anaphase II
What is the term for the random assortment of maternal and paternal chromosomes during meiosis?
Independent assortment
During which phase of meiosis do chromosomes decondense and nuclear envelopes form around each set of chromosomes?
Telophase I
What is the result of meiosis II?
Four haploid daughter cells
True or False: Meiosis is a type of cell division that produces gametes.
True
What is the term for the production of sperm cells in males and egg cells in females?
Gametogenesis
Which phase of meiosis involves the alignment of chromosomes at the equator of the cell?
Metaphase II
What is the term for the process of a sperm cell fertilizing an egg cell?
Fertilization
True or False: Meiosis is responsible for genetic variation in offspring.
True
What is the name of the structure that holds sister chromatids together during meiosis?
Centromere
During which phase of meiosis does the nuclear envelope break down and spindle fibers attach to chromosomes?
Prophase I
What is the term for the division of the cytoplasm following meiosis II?
Cytokinesis
At the end of meiosis II, are the resulting cells haploid or diploid?
Haploid
Which phase of meiosis involves the separation of chromatids?
Anaphase II
True or False: Meiosis is necessary for sexual reproduction in eukaryotes.
True
