The first hand : Mendel in Wonderland

In wonderland, much depends upon the suit and rank of a card. In the time of Alice, the Hearts held power, but since then, the Queen of Hearts has been imprisoned and the Kind of Spades now rules the land.

Families now strive to have children of high suits in order to give them the best chance at a good life.

Suit values are as follows:

Clubs < Diamonds < Hearts < Spades

Conveniently, the inheritance of the suits follows the same order. That is Spades are dominant over all suits, Hearts are dominant over Diamonds and Clubs, and Diamonds are dominant over Clubs.

SC < SD < SH < SS

Two cards come into your clinic to get genetic counseling. They want to know what chance they have of having a Hearts or Spades baby.

Mom is the Three of Hearts

Dad is the Five of Diamonds

They already have three children: a Two of Hearts, a Seven of Clubs, and a Jack of Clubs.

From the information provided above, what do you know?

Is it possible that they can have a Hearts Baby?

Homologous vs Analogous Evolution

I received this video in my inbox his morning from Jerry Coyne’s Why Evolution is True blog. It’s a quick two-minute video outlining how convergent evolution has resulted in extraordinarily similar features appearing in species long after their phylogenetic divergence. In other words, these adaptations are actually analogous, NOT homologous.

The original video appears on phdcomics, where you can find a treasure trove of lab-related humor.
