fertilised egg การใช้

• The fertilised eggs develop into planula larvae which become polyps.
• This colonial animal arises from a single fertilised egg.
• Unfertilised eggs become haploid males; fertilised eggs grow into diploid females and queens.
• Very few fertilised eggs make it to birth.
• The ultimate undifferentiated cell is the fertilised egg.
• The fertilised eggs hatch in about 24 hours and the developing larvae are planktonic.
• The females then moult within a few days and deliver a clutch of fertilised eggs.
• Fertilisation takes place after spawning; the fertilised eggs float just below the water surface.
• They probably arise by the nearly complete separation of a single fertilised egg into two parts.
• Other species are ovoviviparous and the fertilised eggs are retained in the mother's oviduct.
• The water becomes milky with sperm and the bottom is draped with millions of fertilised eggs.
• The female jettisons her fertilised eggs at the water surface by alternating movements of the abdomen.
• Eggs and sperm are ejected into the water and from the fertilised eggs ovoid larvae develop.
• Fertilised eggs develop into planula larvae.
• The fertilised eggs are retained in the mothers'gill chambers where they begin their development.
• Nearby males then release sperm and the fertilised eggs rise to the surface of the water.
• The egg may then divide and up to four embryos may develop from a single fertilised egg.
• Males are occasionally produced at temperatures below and can fertilise eggs that are then spawned by the female.
• The fertilised eggs develop within the tubes, and hatch to produce small ciliated worm-like larvae.
• In a normal pregnancy, trophoblastic cells aid the implantation of the fertilised egg into the uterine wall.
