The main events in meiosis During the first division, chromosomes pair and sections of are exchanged between non-sister chromati
ds as a result of crossing over (prophase I). The nuclear membrane fragments and pairs of homologous chromosomes become aligned on the . One chromosome of each pair is lined up on either side of the equator (metaphase I). The pairs of chromosomes are separated and pulled apart (anaphase I) to either pole to form the first two daughter nuclei (telophase I). divides the cytoplasm and each daughter cell now contains the number of chromosomes.During the second division, the nuclear membrane fragments and individual chromosomes composed of 2 sister become aligned on the equator of the spindle (metaphase II). The pairs of chromatids are separated and pulled apart (anaphase II) to either to form daughter nuclei as the nuclear membranes reform around the new nuclei (telophase II). Cytokinesis divides the two cells into fou
Cytokinesis divides the two cells into four daughter cells.
Explanation:
Meiosis is a type of cell division in which a single cell is divided into four daughter cells. These daughter cells are haploid i. e. half number of chromosomes. This type of cell division occurs only in sex cells of male and female organisms. There are two phases of meiosis. In meiosis 1, a single cell is divided into two daughter cells while in meiosis 2, these two daughter cells again divided into four daughter cells.
Despite the humpback whale and whale shark being similar in size, they are not as closely related as the humpback whale is to the spider monkey, which is far smaller in size. This provides evidence that size of a specie is not a good indicator of its relationship to other species.
