Which of the following statements correctly describes the behavior of ...
Homologous chromosomes move towards the opposite poles:
Homologous chromosomes are pairs of chromosomes that have the same genes at the same loci but possibly different alleles. During anaphase I of meiosis, homologous chromosomes separate and move towards opposite poles of the cell. This is a key step in meiosis I, where genetic diversity is generated through the independent assortment of homologous chromosomes.
Explanation:
- In anaphase I, the homologous chromosomes are pulled apart by the spindle fibers attached to the centromeres.
- The homologous chromosomes move towards opposite poles of the cell, ensuring that each daughter cell will receive one homolog from each pair.
- This separation of homologous chromosomes is essential for the reduction of chromosome number in meiosis, leading to the formation of haploid daughter cells.
- Unlike in anaphase II of meiosis where sister chromatids separate, in anaphase I, it is the homologous chromosomes that segregate.
Significance:
- The movement of homologous chromosomes to opposite poles during anaphase I ensures genetic diversity in the resulting gametes.
- It allows for the shuffling of genetic material between homologous chromosomes, leading to the creation of genetically unique offspring.
- This process also helps in the inheritance of different combinations of alleles from the parental chromosomes, contributing to genetic variation in populations.

Which of the following statements correctly describes the behavior of ...
In anaphase I of meiosis, homologous chromosomes (each consisting of two sister chromatids) move towards the opposite poles. This is a key feature of meiosis I, which reduces the chromosome number by half in each daughter cell, setting the stage for genetic diversity. Unlike mitosis or meiosis II, where sister chromatids separate, meiosis I involves the separation of homologous chromosomes.
