Question

What is the difference in somatic cells and genetic cells?

Define each type of cell and the name of their proliferation or divide.

Answer 1

1: The somatic cells have one copy of each chromosome from each parent, so it has two copies of each total. This is called 'diploid'. A human somatic cell, for instance, has 23 chromosome pairs, or a total of 46 chromosomes

2: The gamete's chromosomes have undergone crossing over, in which a gene or genes have been switched. In other words, the gene for eye color you got from your mother, on the chromosome you got from your mother, hopped over onto the chromosome from your father, and the chromosome you got from your father kicked the gene for eye color that was already on the chromosome you got from your father, back to the chromosome you got from your mother.

3. Somatic cells undergo only one division at a time, mitosis; gametic cells actually double their original, diploid amount of chromosomes to become tetroid (four copies) before undergoing a double division, meiosis. It is during the tetroid stage that crossing over occurs. Four gametic cells are formed at the end of meiosis. However, in the case of eggs, only one useful egg, or ovum, is produced. The other three cells are tiny and useless. On the other hand, sperm are all equal, with four sperm being produced from one round of meiosis.

Hope it helps!
