When a haploid sperm cell fertilizes a haploid egg, what is the resulting cell called, and what is its chromosome status?
Correct Answer
A diploid zygote
Explanation
Fertilization combines the haploid (1N) genetic content of the sperm with the haploid (1N) egg, producing a diploid (2N) zygote — the first cell of the new organism.
