15 Questions
What is the primary purpose of crossing-over during meiosis?
To exchange alleles between chromatids
During which phase of meiosis does crossing-over between chromatids occur?
Prophase I
What is the result of meiosis II in terms of the number of cells produced?
Four haploid cells
What is the main function of tetrads during meiosis?
To exchange genetic material between homologous chromosomes
What occurs during anaphase I of meiosis?
Homologous chromosomes separate to opposite poles
What occurs during telophase I of meiosis?
Formation of nuclear membranes around chromosome clusters
During prophase II of meiosis, what happens to the chromosome pairs?
They separate into individual chromatids
What is the outcome of anaphase II in meiosis?
Chromosome pairs separate into component chromatids
How many haploid nuclei are formed during telophase II of meiosis?
Four
What is the final outcome of cytokinesis in meiosis II?
Formation of four haploid gamete cells
What is the main difference between meiosis and mitosis?
Meiosis involves two cell divisions producing haploid cells, while mitosis involves one cell division producing diploid cells.
What is the meaning of 'diploid' in relation to chromosomes?
Diploid means the cell has a full set of chromosomes, represented as 2n.
Why do gametes produced by meiosis contain mixed genetic information?
As a result of the combination of paternal and maternal genetic information in each gamete.
What is the role of meiosis in a male organism?
To generate sperm cells with half the DNA of the parent cell.
How do haploid cells differ from diploid cells?
Haploid cells have half the number of chromosomes as diploid cells.
Explore the process of Meiosis, which involves one cell dividing twice to produce four sex cells with half the chromosomes of the parent cell. Learn about the difference between diploid and haploid cells in the context of gamete production.
