WebSomatic cells have a diploid set of chromosomes as compared to gametes, which are produced by meiosis (reduction division) and have a haploid set of chromosomes. Many species like wheat have a varied set of chromosomes in their somatic cells, e.g. hexaploid, triploid, tetraploid, etc. Somatic cells are used for cloning by which an identical ... WebIn 1876, a German zoologist Oscar Hertwig (1842–1922) first described the process of meiosis during his study of sea urchin eggs. His theory, which stemmed from the observation of two nuclei in one egg, stated that these nuclei most likely developed due to the integration of substances found within a spermatozoan and an egg. five abiotic factors in the ocean
