Three Big Cookies and One Small：The Weight of Gene Differences

中国的传统观念里，血永远浓于水。

从小就有数不清的人问我。

“你更喜欢你的亲生母亲还是继母？”

我做了四个手的模具，模具原型分别来自我的亲生母亲，和我户口本上的家人:我父亲，我继母， 我同父异母的妹妹。然后我把我的手分别放进这四个模具里，用面粉和糖的混合物来填满我手和模具间的缝隙。用的面粉越多，说明我和这个人的外形差异越大，模糊的指出我和这个人的血缘差异越大。

然后，最后我吃掉了这些饼干。

In the Chinese tradition, only those who are related by blood can inherit the family and can be regarded as family.

I have been asked by annoying relatives since I was very little:

"Do you prefer your stepmother more or birth mother?"

I can not remember my answer at that time. now I want to answer this again with a practice。

I made four molds of my family members’ hands：my birth mother, my birth father, my stepmother, and my half-sister. Then I put my hand in the molds, filling the gaps with a mix of flour and sugar. then measure the weight of the mix that filled the gap.

The more mix I use, the greater the difference in hand shape, vaguely pointed out the greater gene difference.

Finally, I baked these four piles of sugar and flour into biscuits. And ate them.
