What do you think would happen if multiple sperm fused with one egg?

Short Answer

Expert verified

If multiple sperm fuse to one egg the result is something called polyspermy.

Step by step solution

01

Step 1.Introduction

  • Fertilization is the process in which a new cell is formed when two gametes (sex cells) sperm and ova fuse together.
  • Polyspermy describes the fertilization of an egg by more than one sperm.
02

Step 2. Explanation

  • If multiple sperm fused with one egg, a zygote with a multiple ploidy level (multiple copies of the chromosomes) would form, and then would die.
  • If multiple sperm fuse to one egg the result is something called polyspermy, which results in abnormal embryo development. To ensure fusion of a single sperm, the egg becomes rapidly intolerant to additional sperm.
