Know Evidence Page 48 How do you think science can improve our quality of life? Use complete sentences. After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond. “I don’t know.” is not an acceptable answer. Advances in Genetics

Clarifying ?s Information Page 49 selective breeding - choosing a few organisms with desired characteristics to serve as parents for next generation - choosing a few organisms with desired characteristics to serve as parents for next generation - crossing individuals that have identical or similar alleles - crossing individuals that have identical or similar allelesinbreeding increases value of plant or animal Example: disease resistant veggies and cows that give more milk Why? To produce plants/animals w/specific traits Example: disease resistant corn crossed with corn that produces larger kernels – disease resistant/high yield corn Example: disease resistant corn crossed with corn that produces larger kernels – disease resistant/high yield corn Advances in Genetics - crossing two genetically different plants/animals w/the best traits of each going to offspring - crossing two genetically different plants/animals w/the best traits of each going to offspring hybridization Example: Dolly the sheep Example: Dolly the sheep - organism that is genetically identical to the organism that produced it - organism that is genetically identical to the organism that produced it cloning

Clarifying ?s Information Page 49 Summary: - Inserting working copies of genes directly into the cells of an organism w/genetic disorder. gene therapy Advances in Genetics - Genes from one organism are transferred into another organism. - Genes from one organism are transferred into another organism.genetic engineering Why? To improve medicines and food crops – may cure genetic disorders NOT your actual finger prints! NOT your actual finger prints! - An individual’s unique DNA base per sequence is determined by exposing their DNA to molecular probes. - An individual’s unique DNA base per sequence is determined by exposing their DNA to molecular probes.
