Hello everyone.
00:01
So our question is to compare and contrast the mechanisms of polyspermy block in internal versus the external fertilization.
00:38
So the polyspermy means it is when.
00:46
The polyspermy occurs the fertilization of egg, fertilization of egg by more than one sperm.
01:11
More than one sperm.
01:14
So there are several mechanism in order to prevent this polyspermy.
01:21
So before going to the mechanism, we have to understand about what is this polyspermy and what is happening when polyspermy occur.
01:36
So if an egg becomes fertilized by multiple sperm, multiple sperm, then the embryo will gain.
02:03
Various paternal cindrioles.
02:07
So when this happened, there is a struggle for extra chromosome and this will cause us the disarrayment in the cleavage furrow.
02:24
Disarrayment in cleavage furrow and the normal consequence is the.

Death of zygot, death of zygot occur...
