Transcript of Selective Breeding
also can apply to plants or humans
used to have particular genetic traits Selective Breeding By: Jessica Schlundt Farmers, Breeders, and people
needed more healthier/stronger plants and animals to sell and eat The Romans first
practiced selective breeding
to pick out animals easier by specific traits. Animals Plants Humans *also to have specific characteristics of the animal/plant Fun Fact! Intro to: Selective Breeding 101 Selective Breeding Positive Negative VS -allows people to enhance desirable traits in their plants and animals - may cause inbreeding, which weakens the plant/animal and can make them more vulnerable to disease or mutations POSITIVE NEGATIVE ________________________________________________ To Do List: May 2, 2011 Notes: Selective Breeding Presentation!!!

-Scientists tried applying selective breeding to humans (eugenics)
-meant to improve other people's genes
for example: take genes of humans and can: take out genes of diseases in babies (possibly) they can cure a genetic defect before a baby is born clone genes repair genes replace genes create genes that fight off that disease help prepare for a child who will have special needs screening their fetus (unborn baby)
is used by many women to find defected genes A compound manufactured for use as a medicinal drug a requirement for pharmaceuticals that are far beyond amazing compared to experiments before scientists are hoping to create plants/animals with a certain drug by taking advantage of their genes with the help of human hormones but technologies that came after that was gene splicing and human genetic engineering Success! What made Selective Breeding successful is that it let people keep desirable traits and leave out negative ones.
