Quiz 10: Meiosis and Sexual Reproduction

Biology

Meiosis is a nuclear division which involves sexual reproduction and produces four daughter nuclei at the end of the cycle. It is the basis of reproduction in many single-celled and multicellular organisms. Sexual reproduction bestows more variations than an asexual reproduction due to crossing over at prophase, alignments of chromosome during metaphase-1 and fertilization. These factors contribute to several combinations and variations in the offspring's in very few generations compared to mitosis.

Meiosis is a nuclear division which involves sexual reproduction and produces four daughter nuclei at the end of the cycle. It is the basis of reproduction in many single-celled and multicellular organisms. Hence, the correct option is c. Growth of cells, tissue repair and asexual reproduction in many organisms is maintained and done through mitosis. So, the options a, b and d are not correct.

Bdelloid rotifers are microscopic organisms started at least 40 million years ago. These microscopic organisms are having different reproductive mechanisms. Most of them reproduce through asexual reproduction. Bdelloid rotifers are mostly females and are reproduced through unfertilized eggs. They live in the fresh waters and brackish waters. This made them very favorable condition for their survival. These live in conditions where there is less temperature and humidity which prevents drying.
