Full Answer

It takes between three and five days for the zygote to traverse the fallopian tubes into the uterus, where it develops into a blastocyst. The blastocyst, little more than a congregation of cells, implants in the uterine wall, where the amniotic sac grows. The embryo stage follows where the body takes form and internal organs begin to develop. Eight weeks after fertilization, the embryo is developed enough to be considered a fetus. During this final stage, the bodily components that formed as an embryo continue to mature until delivery.

  • Q:

    Can two sperm fertilize one egg?

    A:

    Fertilization of one egg by two sperm is possible, but the resulting zygote is almost never viable because such a zygote would have three sets of chromosomes instead of the normal two. This condition, called triploidy, is usually incompatible with life. Those rare triploid infants that do survive to term have severe and multiple birth defects and rarely live more than a few days.

    What is the life cycle of a swordfish?

    A:

    The swordfish, or "Xiphias gladius," starts as an egg, hatches when the zygote reaches about 0.15 inches long and lives for about 9 years. Eggs are fertilized externally after females spawn anywhere from 1 to 29 million ova. The long bill at the end of a swordfish's nose begins to develop when it reaches 1/2 inch long. Swordfish reach sexual maturity at 5 to 6 years.
