Arise as late as possible.
A 2003 study found that schizophrenia and bipolar disorder could have similar genetic causes that arise from certain problems with genes associated with myelin development in the central nervous system.
The germ cell from which sperm arise is called a spermatogonium. Spermatogonia are diploid cells found in the testes that undergo a series of cell divisions, called spermatogenesis, to produce sperm cells.

No problem at all, just as long as you take the trouble to verify that you and all ofthe possible objects of your communication are using the same system of units.
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
Novel combinations of alleles arise in prophase I and metaphase I.
yes according to cell theory all cells arise by division in previously existing cells.
Arise as late as possible.
this is not true
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
you are in my science class.
Species that arise due to genetic isolation such as the carrion crow (Corvus corone corone) and the hooded crow (C. c. cornix)
Sample answer: Engineered traits such as herbicide resistance could transfer to weeds and create "superweeds."
Hydrocephaly can arise from an inherited genetic deformity as a congenital condition. Acquired hydrocephaly happens sometime during birth or a point afterward.
The cause of vitiligo is unknown, but research suggests that it may arise from autoimmune, genetic, oxidative stress, neural, or viral causes.
Because of mutations that arise during meiosis.
