#1 Phenomenon or no, somebody'd have some spaining to do at my house.

#3 Maybe she's a chimera.

#4 Could be. But light skin, light hair and blue eyes are the result of simple recessive genes. All you need for them to show up is for the embryo to inherit one of the genes from each parent. The mother carries one copy of these genes from her mother and the father carries at least one copy as well, as their older daughter proves.

What is unusual is that in the case of the lighter twin, two copies of the genes for skin, eyes and hair all got inherited at once. It's statistically rare, but not otherwise surprising so far as I can tell.

#5 Like cats. My cat--grey tabby with a trace of pekinese--had the following litter: 1 snow-white, 1 black and white, 1 grey siamese, 1 calico brown'n'black and 1 orange tabby that did not make it. How did she manage to pull that off is a mystery to me.

#6 How did she manage to pull that off is a mystery to me.

Catting around.

#8 2x4, going back a generation, the trace of pekinese is certainly impressive.

#9 Grunter, I realized that the term is archaic or may have been used where I grew up. It is a variant of short-faced persian short-hair cat.

#10 These twins are destined to torment the boys as they grow older. "Hmmmm ... chocolate or vanilla?"

#11 In junior high school, I knew a brother and sister (not twins) named Sullivan. The brother was your standard Mk. 1 Mod. 0 Irish-American kid; the sister had dark hair and a latte complexion. Took me several weeks to realize they were from the same family.
