First of all, how do you guys do it? Second of all, seriously? How can that even be? Wait... how can you even research that? Weren't there more animals in the past? Where or what is RRL?
Not true, I know for a fact that duck fetus is a delicacy in the Philippines and I imagine there's more
I have seen those before I dunno how people can eat them I seen my mother eat them though. Spoiler: Picture for Reference
It's still eaten before said animal would be born. Also the chicken eggs we eat are unfertilized and thus would never grow to be chickens anyway.
I think that guy just found the entire argument between both sides funny and did not want to spark a flame war here so he mention that before he pointed out the fight(between GT and RRL) here.
I think it's best to leave this discussion here and u can post a fun fact like this Spoiler According to the Romance of the Three Kingdoms, Shu general Zhuge Liang had to defend a town with a mere 100 troops against an army of 150,000. He hid his men, flung open the gates, and sat on the walls playing a lute. The opposing general of Wei, Sima Yi, certain it was a trap, ordered a retreat.

Not all the gene on your body came exclusively from you father or mother. Some of your gene in your body also come from bacteria, virus, or even your unborn twin. Some of your cell could even was not yours. Now, for the interesting case: 1. A pregnant woman may had their daughter or son cell embedded in her brain, lung, heart, liver and kidney (and God's know how many others organ also infiltrated by the fetus cell). That's why woman with many child had less risk to get Alzheimer. Her brain was littered with new neuron from the fetus. 2. A twin may share their cell with each others. So a portion of cell of a twin may came from her/his counterpart. Please remember that not all twin will get born. Some of the twin was naturally aborted early in fetus development that it could absorbed by the other. (This explain why a person may had 2 blood type. He also got his own blood cell and his unborn twin fraternal brother blood cell.) 3. A woman conduct a paternity test in front of the court. The result declared that she share no gene with them. Then it was revealed that some of her ovum (egg cell) was microchimeric (possibly came from her unborn twin sister). Readn this article make me want to incorporate this into a story somehow...... So much plot potential.........
To you who knows many facts (like @Yukkuri Oniisan and @Nimbus), I have a question for you: "Its is possible for a twin to be born from a zygote, but can an XX XX twin turn into an XX XY twin?" For those who doesn't understand: "Is it possible for a male and a female twin to exist from one zygote?"
NOPE. But the reverse XY turn into XX is possible Assuming we are talking about maternal twin [one egg one sperm] and not fraternal twin (one or two egg, two sperm, it can result in different gender twin ) The whole story is like this : 1. The actual zygot is XY (male). 2. When the zygot split into twin. The Y chromosome was forgotten to be replicated [This is a very rare occurrence). So the twin was like: First twin: XY (Male) Second twin: XO (Female, but infertile) So you got a twin with one fertile Boy and one infertile Girl. But this is not interesting so: 3. Then the second twin had X chromosome doubling/duplication: Second Twin : XO --> XX (full fertile female) [Actually this is a ultimate rare occurrence] 4. So when they born, you got an (almost) identical maternal twin of different gender. Of course, this will be a very rare happening.... The chance I win national lottery is bigger than this happening...
