In class today we finished our origami genes and also added to our genetics vocabulary list. Understanding the language of genetics is essential to being able to really understand how genetics work and make predictions about the genetic make up of organisms. Here are the words we added today.
Hybrid: Offspring receiving different alleles from each parent Dominant: The form of an allele that covers up the other form of an allele Recessive: The form of an allele that is covered up by the dominant allele Genotype: refers to the genetics make up of an organism (represented by pairs of letters TT, Tt, tt) Phenotype: The physical traits of an organism, more simply what an organism looks like (Tall, short) Homozygous: a pair of alleles that are the same AA, aa, BB, bb Heterozygous: When a pair of alleles are different Aa, Bb, Cc

Today was all about DNA. We completed our first round of genetics notes as well as watched the video below about what is DNA and what does it do. Tomorrow we start NWEA testing, which we will finish Thursday. Friday we will continue exploring genetics. In class today students took a short test over what we've done in class so far. Then we drew diagrams showing the levels of organization in an organism. Starting with the body of an organism going down to single alleles, this diagram shows increasing complexity in living creatures.
