Explanation
The ovum (egg cell) formed after fertilization is diploid. Fertilization is the process by which a sperm cell, which is haploid, combines with an egg cell, also haploid, to form a diploid zygote. The zygote contains a full set of chromosomes, with half of the genetic material contributed by the mother (through the egg) and half by the father (through the sperm).
