And I'm back! Sorry for not writing yesterday, you know those orthodontist appointments! My teeth are so sore! It really stinks! Anyways, today I get to write on Punnett squares. Nope, not Punent squares... that's not even a word!
A Punnett square is used to show traits that can be inherited from two parents, to their offspring. Punnett squares are really useful even though they are simplified to the max. A Punnett squares are easy to make and use as long as you now the difference between dominant traits and recessive traits. A Punnett square is a square divided into fourths. It very simple they way Punnett squares work so don't stress like I did.
Let's say this,
A woman with brown eyes (dominant trait) married a man with blue eyes (recessive trait) and eventually had kids. What are the possibilities that their child will have blue eyes. Make a Punnett square! The possible genotypes for the mom could either be BB or Bb. The dad would have to be tt because he has a recessive trait. So on the top of the Punnett square put BB (we will do the "Bb" trait later). Remeber that the BB trait is for the femaleand the bb trait is for the male. You can draw pictures to help remind you of who is who! Can't wait to see what you find!
