This is Mitosis, which occurs with all nucleated somatic (body) cells, but not in germ (sex) cells.
Germ cells, aka gametes, on the other hand, undergo Meiosis, a process of nuclear cell division whereby 1 parent cell gives rise to 4 daughter cells. These daughter gametes, either sperm or egg cells, all have 1/2 the number of chromosomes as the original parent, termed "haploid." The genes of these gametes were also randomly assorted and crossed-over, allowing a shuffling of their chromosomes' genes.
Answer:
The correct answer is option c.
Explanation:
Starting from the initial primates to the hominids, and eventually, to Homo sapiens, the brain of humans has grown spontaneously. The volume of the brain has increased with the evolution of humans, that is, starting from about 600 cubic centimeters in Homo habilis to 1600 cubic centimeters in Homo neanderthalensis. The Homo neanderthalensis was the hominid with the largest size of the brain, that is, with the maximum cranial capacity. The enhancement in the size of the brain ceased with neanderthals. After that the shrinking of the brain size took place.
