During which process does independent assortment of chromosomes occur quizlet?
During which phase(s) of meiosis does independent assortment occur and what is the significance of this process? The homologous chromosomes separate. The chromosomes of each pair are pulled to opposite poles of the cell by the spindle fibers. The chromatids do not separate at their centromeres.
Does Independent Assortment happen during metaphase 1?
During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. … This is important in determining the genes carried by a gamete, as each will only receive one of the two homologous chromosomes. This is called Independent Assortment.
Does independent assortment occur in mitosis?
While in mitosis, genes are generally transferred faithfully from one cellular generation to the next; in meiosis and subsequent sexual reproduction, genes get mixed up. … Thus, because of independent assortment, recombination, and sexual reproduction, there are trillions of possible genotypes in the human species.
Does independent assortment occur in metaphase II?
This occurs only in metaphase I. In metaphase of mitosis and meiosis II, it is sister chromatids that line up along the equator of the cell. … The daughter cells each have a random assortment of chromosomes, with one from each homologous pair.
What is independent assortment of chromosomes?
The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. … During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.
Does Independent Assortment happen in metaphase or anaphase?
When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.
What occurs during independent assortment in meiosis?
Independent assortment is the process where the chromosomes move randomly to separate poles during meiosis. A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes.
