Study Notes
Independent Assortment in Meiosis
- Independent assortment occurs during metaphase 1 of meiosis 1.
- Chromosomes line up in multiple different orientations, allowing for genetic variation.
- The arrangement of one pair of homologous chromosomes does not influence how other pairs align, affirming that the process is random and independent.
- Chromosomes' orientation during this phase can lead to diverse genetic combinations in offspring.
- True: Chromosomes aligned on the left side of the metaphase plate will migrate to different cells than those on the right side.
- Independent assortment plays a crucial role in determining which alleles will be present in each newly formed cell.
- True: Independent assortment can also occur during meiosis 2.
- Specifically, it happens during metaphase 2 of meiosis 2.
- If the sister chromatids of lower chromosomes do not cross over, their genetic material remains identical; hence, independent assortment in this phase does not impact genetic inheritance.
- Independent assortment in metaphase 2 facilitates the random lining up of sister chromatids, leading to an array of genetic variations in gametes.
