Detailed explanation-1: -What percentage of chromosomes are handed down by a sperm cell? A)75%.
Detailed explanation-2: -Sutton demonstrated that the number of chromosomes was reduced in spermatozoan cell division, a process referred to as reductive division. As a result of this process, each gamete that Sutton observed had one-half the genetic information of the original cell.
Detailed explanation-3: -Sperm and eggs end up with the DNA they get through a process called meiosis. When cells normally make new copies of themselves, each of the new cells ends up with 46 chromosomes (at least for humans). However, in meiosis, each new cell ends up with 23.
Detailed explanation-4: -Mitosis: Cell division in Asexual Reproduction. 2 Daughter cells exactly like the parent. Heredity is passed to offspring: 100% DNA from 1 parent.
