<p>The main purpose of meiosis is to produce genetically unique gametes for reproduction. Meiosis achieves genetic uniqueness by shuffling and recombining genetic material through crossing over and independent assortment, resulting in four genetically unique daughter cells.</p> Signup and view all the answers

<p>During prophase I of meiosis, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down. This is significant because it allows for the pairing of homologous chromosomes and the exchange of genetic material through crossing over.</p> Signup and view all the answers

<p>In anaphase I, homologous chromosomes separate, whereas in anaphase II, sister chromatids separate. The significance of anaphase I lies in reducing the number of chromosomes by half, while anaphase II ensures that each daughter cell receives a complete set of chromosomes.</p> Signup and view all the answers

<p>Meiosis contributes to genetic variation through crossing over, which shuffles genetic material, and independent assortment, which randomly distributes chromosomes. Crossing over increases genetic diversity by creating new combinations of alleles.</p> Signup and view all the answers

<p>The spindle assembly checkpoint ensures that the spindle fibers are properly attached to the kinetochores before anaphase begins, preventing chromosomal misalignment and ensuring proper chromosomal segregation. This checkpoint is crucial in both mitosis and meiosis, as it prevents chromosomal abnormalities and maintains genomic integrity.</p> Signup and view all the answers

<p>The chromosomal alignment checkpoint ensures that all chromosomes are properly aligned at the metaphase I plate before anaphase I begins, while the pachytene checkpoint ensures that all chromosomes are properly paired and synapsed during prophase I. These checkpoints work together to ensure accurate chromosomal segregation and genetic recombination during meiosis.</p> Signup and view all the answers

<p>Mitosis produces two daughter cells with the same number of chromosomes as the parent cell, whereas meiosis produces four daughter cells with half the number of chromosomes. This difference reflects the distinct functions of mitosis in somatic cell growth and repair, and meiosis in gamete production and genetic recombination.</p> Signup and view all the answers
