Presentation transcript:

Warm Up 3/9/15 In your own words, what is the Law of Dominance? If a mother who is heterozygous for blood Type A and a father who is heterozygous for blood Type B decided to have children, what could the possible blood types of these children be?

Warm up 3/11-12/15 Draw a picture of nondisjunction and label its parts. Are genetic mutations good or bad? Why?

Biology 1 Mr. Hedrick and Mrs. Heins Genetic Engineering

Genetic engineering Making a change in the DNA code of an organism Not a natural process Ex: Genetically Modified Food

Stem cells Undifferentiated cell

Presenting Guidelines: After reading, the following questions must be answered and presented to classmates. Define any unknown terms. What subject is your article about? What does that subject have to do with genetic engineering? 2 interesting facts How is the process done?

Stay and stray Today we will be using the stay and stray method. One student will stay at each station while all of the other students in the group will move one spot. I will then choose one person from the “stray” group to “stay” and explain what the article was to the next “stray” group.

Selective breeding Passing wanted genes to the next generation by allowing fertilization of desired organisms Ex: Turkeys, Frogs

Selective breeding

Selective Breeding

Inbreeding Breeding individuals that are genetically similar Ex: Plants and Animals: Protective Mechanisms

Hybridization Crossing dissimilar individuals Ex: Mule, Liger

hybridization

Recombinant DNA Joining together DNA from 2 or more sources, changing the genetic composition of living organisms The DNA is created artificially Ex: Diabetes (insulin and bacteria)

Cloning Genetically identical organism produced from a single cell Ex: dog

DNA Fingerprinting Analyzing section of DNA that vary from individual to individual These section may have little or no genetic value Ex: Crime Fighting

Gene therapy The process of changing a gene to treat a medical condition Ex: Treating Cancer, Diabetes

Transgenic Organisms produced by the insertion of recombinant DNA into the genome of a host organism
