  • Hello, my name is Jacob and I am going to be telling you all about Genetics!
  • First, there are genotypes, which are the genetic codes for a trait. These include Homozygous Dominant, Homozygous Recessive, and Heterozygous.  Examples for those in order could be HH, hh, and Hh.
  • Next, we have phenotypes, which are the physical appearances for a trait. These usually include hair color, skin color, and eye color. 
  • Also, traits can be either inherited or acquired. Inherited traits are heights, long arms, and good vision. Acquired traits are quick reflexes, sports skills, and IQ. 
  • Next, there is something called a pedigree. This is a family tree that starts with the oldest relatives on top. On the left shows the oldest of that generation. These pedigrees have a trait shown that some people have in that family. The trait is shown if a person´s circle or square is shaded in.
  • Finally, you can find the genotype of an offspring produced by 2 organisms by creating a punnett square. SImply write the genotype of one organism at the top 2 spaces of the square and the genotype for the other on the left. Then cross over the letters to produce the offspring and you can see what percent of what traits they have.
