Question

the result of polyspermy in humans is _______.

1. multiple births
2. a nonfunctional zygote
3. interruption of meiosis
4. mitotic insufficiency

Explanation:

Polyspermy in humans (fertilization by multiple sperm) leads to a zygote with abnormal chromosome number, making it nonfunctional. Multiple births result from multiple conceptions, meiosis interruption is unrelated, and mitotic insufficiency isn't a result of polyspermy. So the correct option is 2) a nonfunctional zygote.

Answer:

1. a nonfunctional zygote
