Patrick’s Question

“Why don’t I have curly hair too?”

A common question in my house…

Patrick:

Curly Hair or No Curly Hair??Grandpa

CC = Curly haircc = Straight hair

ME..

Now it all makes sense…

It makes perfect sense that Patrick’s maternal

grandfather had dominant heterozygous allele’s for

curly hair, while his maternal grandmother had recessive

homozygous allele’s.

This passed the curly hair trait on down to

me, where as my sister has straight

hair.Patrick’s father must also have

the dominant heterozygous allele for curly hair. Making it possible for our children to have either

straight or curly hair.

This question has now been answered thanks to our pedigree chart..
