Genetic Engineering

LMAO. That's a great idea...

Personally, I'm not concerned about the safety of GM foods. It's essentially doing what the plant can do by itself anyway- cross breeding, albeit there's microscopic DNA work instead of pollenating differently.

No, it is very very very very very different.

Iâ??m going to take the time and break this down.

Mendel bred peas,. So what were really talking about is genetic engineering and selective breeding.

I will explain the difference. But I am going to assume some knowledge of evolution, sorry if it confuses.

Genetics info you need to know:
-Phenotype --- is what genes are expressed. Ie. What the organism looks like
-Genotype----- The genetic make up of an organism. Defined by the genes present.
-Gene--- a string of DNA that codes for a particular trait. EG. Eye or hair colour.
-Allele--- different possible options a gene can have.
EG. For the Gene â??eye colourâ?� the alleleâ??s are: brown, blue, green and so on
-for each gene there are two alleleâ??s, because we have two sets of each chromosome (one from your mom and the other from your dad. Well in some cases the second is from the mail man.)
-Mutations --- are the only known source of Alleleâ??s and genes. Mutations are accidents when transcribing or translating DNA or RNA.
Homozygous- the two alleleâ??s for a gene in an organism are the same
Heterozygous- the two alleleâ??s are different

Theory of plant breeding: (its simple)
-Lets say your goal is to grow nice big tomatoes
-You grow lots and lots of different plants
-look through them and find the ones producing the most desirable fruit.
-Take these two plants, force them to pollinate each other.
-Then you get the seeds from the plant. (it gets complex here)
-Since these seeds are from your two strongest (genetically) plants all the seeds will have a different mix of the plants.

-These seeds will come out in the ratio 1:2:1
1â??or 25% of the seeds will have a homozygous genotype for the desired trait, with the desired allele!
2---or 50% will have heterozygous genotype for trait, have both alleleâ??s
1â??25% will have homozygous, with two undesired alleleâ??s
(assuming each of the parents were heterozygote for the gene)

This is what Mendel Taught us.

I will continue. Please donâ??t comment yet.
