Applications of human genome project
Gene therapy: puts normal genes into human cells to correct genetic disorders. EX: Cystic fibrosis nasal spray
Cystic fibrosis
1/20 white Americans have this. This is the thickening of mucus.
Monohybrid cross
a cross with only one trait
Inbreeding
Breeding close to get a homogeneous offspring
Recombinant Bacteria in agriculture
fertilizer free plants
Pedigree Analysis
Chart showing one trait being carried over many generations
Polygenic Inheritance
Traits that are controlled by two or more genes, bell curve. EX: Height, weight, shape color.
Electrophoresis
A device used to separate DNA by charge and length
Recombinant in medicine
human growth hormone and insulin
Sex linked inheritance
Traits located on the sex cells. EX: Colorblindness, hemophilia.
Dihybrid cross
a cross with two traits
Ways to study Human inheritance
Pedigree analyses, twin studies, population sampling, karyotyping
PKU
Can be regulated with diet at a young age
Transigenic organism
Plants and animals that have functional recombinant DNA. The three steps are Isolate the foreign DNA, attach DNA to "vehicle" transfer vehicle into host organism.
Human genome project
Identified 20,000-25,000 genes in human DNA
Selective breeding
Breeding to make one give one specific trait to the offspring
Recombinant bacteria in Industry
cleans oil spills
Genetic Engineering
Same thing as Recombinant DNA. Cutting and recombining DNA from different sources.
Tay-Sachs
Common in Amish and Jews.
Simple dominant traits
Free earlobes, tongue roller, widow's peak, straight thumb
Karyotyping
A way to check for abnormality in a baby before it is born, by taking pictures of the chromosomes and lining them up.
Environmental Influences
Temperature, light, nutrition, chemicals.
Hybrids
A cross between two different breeds to get a certain trait
