Fertilization occurs when ' Two gametes come together and chromosomes combine'. :)
Answer: the correct answer for the fill in the blank is- Gametes come together and chromosomes combine.
Fertilization is a process in which sex cells ( also called male and female gametes that are haploid) are fused together and form zygote ( diploid) that eventually develops into new organism.
There are two types of fertilization that is internal ( inside the body) and external fertilization ( outside the body).
