De novo mutations occur in the reproductive cells of parents and are passed on to the child. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube.

I recommend that you include potassium when fertilizing late spring during the summer and again in the late fall prior to the allow the grass to harden off before cold frosts appear. Biologists thought this made sense. Most lawn care companies will integrate potassium applications into traditional fertilization plans. Once fertilization takes place this newly fertilized cell is called a zygote.

In humans beginning at puberty the cells that produce sperm divide and copy their. Evidence suggests that most de novo mutations in a child come from the sperm that helped create that child and relatively few mutations come from the egg.
