In addition, the random assortment of tetrads on the metaphase plate produces a unique combination of maternal and paternal chromosomes that will make their way into the gametes. Figure 3. Random, independent assortment during metaphase I can be demonstrated by considering a cell with a set of two chromosomes (n = 2).
In which phase of meiosis does independent assortment of chromosomes occur?
In anaphase I of meiosis, each pair of homologous chromosomes segregate independently of all other pairs of homologous chromosomes. The assortment is dependent on how the homlogs line up during metaphase I.
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.
What is the correct order of these meiotic events?
The correct order of mitotic events which occur during meiosis is: Formation of synaptonemal complex, recombination, separation of homologous chromosomes, separation of sister chromatids.
What is the difference between meiosis 1 and meiosis 2?
There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.
Which best describes what happens between meiosis I and meiosis II?
Answer Expert Verified. The correct answer is (b)During meiosis I, two haploid daughter cells are formed due to the separation of homologous chromosomes, and during meiosis II, four gametes are formed due to the separation of sister chromatids.
What are the essential features of meiotic process?
Features of Meiosis
It results in the formation of four daughter cells in each cycle of cell division. The daughter cells are identical to the mother cell in shape and size but different in chromosome number. The daughter cells are haploid. Recombination and segregation take place in meiosis.
