Some Vocabulary! Heredity: the passing of physical characteristics from parents to offspring ( you will learn about this later. PAY ATTENTION!) Genotype: a genotype is an organism’s genetic makeup, or allele combinations Sex linked genes: A gene that is carried on the X or Y chromosomes Hybrid: An organism that has two different alleles for a trait; an organism that is heterozygous for a paticular trait.

Punnett squares, Mendel’s work:
How to do a punnett square! A B Boxes Probability A )AA % AA 2)AB % AB A )AA 4)AB

Using Punnett Squares To Track Traits
Parent 1. Blue Eyes (genotype bb) Note: Genotype Parent 2. Brown Eyes(genotype Bb) for brown hair can be: BB or Bb Children: 50% chance of being Bb (Brown Eyes) 50% chance of being bb (Blue Eyes)
5
Blood Typing There are three types of blood- A,B, or o.o is recessive, and A and B are dominant.Therefore, blood that is Ao or Bo is still considered A and B because A and B are dominant. Example:
6
Pedigree Charts A pedigree chart demonstrates the traits of a family and who does and doesn’t have a particular trait. A pedigree chart is similar to a family tree due to the fact it presents all the family names
7
Genetic Mutations Cystic fibrosis- Genetic disorder where the body produces abnormally thick mucus in the lungs and intestines Sickle Cell Disease- Red blood cells cannot carry as much oxygen Hemophilia- A person’s blood clots slowly or not at all Down Syndrome- People who have Down syndrome have a degree of mental illness and retardation.
