What is polyspermy in humans?
Polyspermy is when more than one sperm penetrate one egg during conception. Normally, there are blocks to polyspermy because humans are generally monospermic - only one sperm and one egg can create a viable zygote. Thus, there are biological blocks to polyspermy in humans.
Why is polyspermy bad for fertilization?
Polyspermy is bad for fertilization because it results in the fertilized egg having an abnormal number of chromosomes, which can lead to developmental abnormalities and prevent the embryo from developing properly.
Why polyspermy bad?
Polyspermy, the fertilization of an egg by multiple sperm, is detrimental because it leads to an abnormal number of chromosomes, resulting in genetic imbalances. This can cause developmental issues, embryo lethality, or infertility. In many organisms, mechanisms exist to block polyspermy, ensuring that only one sperm fertilizes the egg to maintain proper genetic integrity.
Are humans the result of a mindless chemical reaction?
Religious people believe that such a possibility is ridiculous. We see humans as being the result of creation by God.
Eye color in humans is the result of?
Melanin.
What does dispermy result in?
Dispermy is a type of polyspermy that occurs when two sperm fertilize one egg. This results in an embryo with triploid (3n) chromosomes, which is typically non-viable and leads to developmental abnormalities or pregnancy loss.
What causes the slow block to polyspermy?
The slow block to polyspermy is caused by changes in the egg's membrane potential and increased intracellular calcium levels, which prevent additional sperm from fertilizing the egg. This physiological response allows only one sperm to successfully fertilize the egg and prevents the formation of abnormal embryos with multiple paternal contributions.
What damage have humans caused to the forbidden city.?
B.did not result in a Japanese surrender.
Are humans part of a shark's normal diet?
Humans are not a normal part of any shark's diet. There are only about 60 shark attacks on humans worldwide per year, few of which result in death.
What is an aliment in a sentence?

What are two examples of organisims that have developed differences as a result of divergent evolution?
Humans and monkeys
Is it all right to eat humans if you are a humans?
How do you determine what it right? If polling answers.com is your method, then certainly "NO" will be your answer. I suspect that consulting your conscience will yield the same result.
