Problem : Which of the following figures represents likely resulting cells of the first meiotic division?
Problem : Which is the longest phase of meiosis?Prophase 1 can last up to 90% of the entire duration of meiosis because the very important genetic reassortment event occurs during it.
Problem : Are the sister chromatids present in a cell in prometaphase 1 identical?No. While they are very similar, sister chromatids in prometaphase 1 are slightly different because of the small segment of crossover between parental homologous pairs that results from prophase 1 genetic reassortment.
Problem : Fill in the blanks. During mitosis, chromosomes are separated by microtubules attached to their their _________. In meiosis, on the other hand, a microtubule attaches to a structure called a _________.Kinetochores or centromeres. Chiasma.
Problem : What is the main difference between the events of anaphase 1 and those of mitotic anaphase?During anaphase, maternal and paternal sister chromatids are separated to opposite ends of the cell via microtubules. In anaphase 1 of meiosis, the maternal homologous pair and the paternal homologous pair are separated to opposite ends of the cell before division.
