This week in Biology, we learned about Mendelian genetics. In order to do an offspring inheritance simulation, we flipped coins to demonstrate dominant and recessive allele. This determined the phenotype of the offspring's hair, eyes, ears, mouth, skin, gender, and nose. My wife Graham and I gave birth to a beautiful child on Wednesday. On Friday, we took notes on sex-linked genes as well as dihybrid crosses.
In sex-linked traits, women have two X chromosomes, while men have one X chromosome and one Y chromosome. Because of their single X chromosome, men will express whatever allele no matter dominant or recessive. A dihybrid cross is the crossing of two organisms that differ in two traits.
