What is this?
How do scientists manage genetic disorders?
a picture of all the chromosomes in a cell
help people understand their chances of having a child with a particular genetic disorder
3 methods for developing organisms with desirable traits
selecting organisms with desired traits to be parents of the next generation
farmers saving seeds from healthiest plants for replanting
crossing two individuals with similar characteristics/genetic similarities
Breeding a male and female turkey that are both plump and grow quickly to generate fat plump, fast growing chicks
crossing two genetically different individuals
crossing corn that produces many kernels with corn that is resistant to disease to get a generation of corn that is both resistant to disease and produces many kernels
an organism that has exactly the same genes as the organism from which it was produced
genes from one organism are transferred into the DNA of another organism; used in medicines and crops
example of genetic engineering in bacteria
Example of genetic engineering in animals
Inserting copies of a gene directly into a person's cells to correct genetic disorders
Concerns about genetic engineering
all the DNA in one cell of an organism
the goal of the Human Genome Project
DNA technology used in Human Genome Project that identifies people and shows whether they are related
True or False:
Unless your an exact twin, your DNA is unique to you.
