The baby is adorable! I learned in biology that everything that involves your eyes comes through your mother. Let's see if it's true with this baby or whether my teacher lied to me

It depends on the genotypes...Brown is the dominant allele, blue is recessive.
Hehe, if we do a punnet square:
B=brown b=blue
Frederik has blue, he must be homozygous recessive for him to show blue eyes: he is bb
Mary: Depends...if everyone in her family has brown eyes, then she is most likely BB (homozygous dominant), but it also possible her mom or dad were heterozygous...so she could be Bb, potentially (which is what Alexandra has to be seeing as Nikolai and Felix both have blue eyes).
bb x Bb
B b
b Bb bb
b Bb bb
Sooooo, we can see that 50% of their kiddies will have blue eyes, and 50% will have brown eyes (obviously not that perfect in real life.)
If Mary is BB, then:
bb x BB
B B
b Bb Bb
b Bb Bb
100% brown

Did Mary's mom have blue eyes? Does Mary's Dad have blue eyes? If either of them did, then Mary is Bb for sure and the baby might have blue eyes...but if Mary's genotype is homozygous dominant, then the baby HAS to have brown eyes.

Hehe, a little biology lesson.

He's a very cute baby regardless of eye colour. He looks like a little old man. So small! I hope they don't name him Christian. Christian should be one of his middle names, but he should have a name that fits him, and it'd be nice if it fit with his cousins' names, Nikolai and Felix which sound more modern than "Christian" or "Frederik"...at least to me.
