What is the result of polyspermy
Which block to polyspermy is long lasting?At fertilization, eggs are exposed to multiple sperm but entry of more than one sperm causes polyploidy, polyspermy, which results in abnormal embryo development.The slow block to polyspermy in the sea urchin embryo consists of a physical barrier to further sperm penetration into the egg.What prevents polyspermy from occurring?How do they function in reproduction?
Proteases and acrosin are enzymes.It is composed of cytoplasm enclosed by an outer layer known as the cell membrane.In most animals including mammals, echinoderms, and teleostei, the penetration of only one sperm into an egg is ensured at fertilization because the entry of two or more sperm is … fertilization 2:On the other hand, the course may be in between the spermatozoa of two different males for fertilizing the egg.What is the slow block to polyspermy?
During fertilization in animals, a haploid egg nucleus fuses with a haploid sperm nucleus to restore the diploid genome.How is polyspermy prevented in humans?
