Crossing over occurs only between nonsister chromatids within a homologous pair of chromosomes, not between the sister chromatids of a replicated chromosome. Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). At the end of this phase, the nuclear membrane dissolves. Why sexual reproduction so common in higher multicellular organisms such as humans? Either one of each pair can go to either pole. What would happen if organisms produced reproductive cells through mitosis instead of meiosis? While asexual reproduction only involves mitosis, what does sexual reproduction involve? Mendel found that paired pea traits were either dominant or recessive.When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Meiosis produces haploid cells and mitosis produces diploid cells.
