One method of protecting the genetic identity of a population is the inability of spermatozoa to fertilize ova of a different species This is called?
Gametic incompatibility is a method of protecting the genetic identity of a population. In this method, sperm transfer occurs but the egg is not fertilized.
Can multiple sperm fertilize one egg - Isn't it possible in theory for multiple sperm to enter the egg at the same time?
Semen is an organic fluid, also known as seminal fluid, that usually contains spermatozoa . It is secreted by the gonads (sexual glands) and other sexual organs and can fertilize female ova . In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa and provide a medium through which they can move or "swim". The process that…
Fertilization normally occures in the uterine tube within a day after ovulation. Sperm cannot fertilize an egg until they have undergone "Capacitation". Capacitation occures after the spermatozoa(1) miz with secretions of the seminal vesicles and (2) are exposed to conditions inside the female reproductive tract. The epididymis secretes a substance that prevents premature capacitation. Anatomy and Physiology book, second edition p.703 and p.766 Alvin Community College EMT-I student.
it is important for 1 sprem to fertilize a human egg (Ova) in order to start the conception process. If 2 sprem Cells fertilize the 2 DIFFERENT Ova the mother will have "Fraternal Twins". However, if 2 sperm cells fertilize the SAME Ova (egg) the mother will have "Identical Twins". I hope that is the answer you were looking for?
