Fertilization starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Fertilization.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Describe what happens to the zygote immediately after fertilization.
Explain the difference between internal and external fertilization.
Explain the importance of genetic variation resulting from fertilization.
Explain why external fertilization is more common in aquatic animals.
Explain why fertilization is considered a random process.
Explain why only one sperm fertilizes an egg, even though millions are released.
Fertilization in humans usually occurs in which part of the female reproductive system?
What is fertilization in the context of sexual reproduction?
What is the significance of fertilization in sexual reproduction?
What prevents more than one sperm from fertilizing an egg?

A scientist observes that in a certain species of fish, fertilization occurs outside the body and the eggs are released into the water. What are two major challenges faced by gametes in this type of fertilization, and how might the species overcome them?
Describe the role of calcium ions (Ca2+) during the process of fertilization in animal eggs.
During fertilization in animals, what is the significance of the cortical reaction, and how does it prevent polyspermy?
