Roland Posted January 3, 2007 Report Posted January 3, 2007 Could a double yolked egg be fertilized by different sperm. Are the two yolks split in the egg, or is it a case of the hen releasing two seperate fertilised ovum at the same time, each being fertilised by a different sperm cell, each in it's own yolk and being encased in the same shell. Not sure myself, anyone out there have an answer.
Guest Posted January 3, 2007 Report Posted January 3, 2007 Oi! thats a dozen questions in one there. I don´t think there is a single easy answer to it either. Ovum are definite single Sperm set-up. Soon as a sperm penetrates ovum outer membrane, chemical reaction makes it impermeable to any others. Don´t know how double yolk works tho, or cause.
Roland Posted January 3, 2007 Author Report Posted January 3, 2007 Just trying to liven up the banter and get 'Pigeon Talk' a little more rife like lol. Mind then a good old heated debate on the side will have ratings going through the roo f lol.
Guest ben Posted January 3, 2007 Report Posted January 3, 2007 Of course it can roland,and has happened in human`s, fraturnal twins mean 2 seperate eggs fertilized by seperate sperms. Indentical twins mean egg splitting in 2 after being fertilized by a sperm. So if the hen spreads and gets jumped by a cock quicker than her mate..BINGO...
symbro Posted January 4, 2007 Report Posted January 4, 2007 why would it have to be a different cock? if this was possible then it would just to sperm from any cock. the same or different..
Roland Posted January 4, 2007 Author Report Posted January 4, 2007 Just answered my own question. Double yolk eggs are the result of two different ova being released by hens whose laying cycle is not yet hormonally synchronized. Hatchibility of these eggs is very low. Not enough room for both chicks to survive. Check the following link. http://ag.ansc.purdue.edu/poultry/ces/educators.html Therefore no genetically identical twins.
