Cloning is an important part of advancing science. You have to ask yourself this question though...If you cloned yourself and had sexual relations with your clone, would you consider yourself gay?
It's possible. Your family members can influence you to become shy if they're the same way. I do believe there are traces of your parent's personality in you and it could include shyness.
Why have we developed gm crops?
To increase their resistance to disease and predation. To improve the yield. To allow crops to grow more quickly and in more adverse conditions. To reduce starvation in the world.
Bacterial DNA is used frequently in genetic engineering because?
it is found in the cytoplasm as a simple circle.
I got this from google. The first person was Jonathan Hutchin.
Genetic differences between populations tend to be reduced by?
Gene flow tends to reduce diffences between populations.
Can plant gene cloned to human gene?
Yes, but that does not mean that any viable creature might develop. There are very few limits to what genes can be inserted into what - quite a few creatures have gained fluorescing genes from jellyfish, including mice, and antifreeze genes from an arctic fish have been inserted into a soft fruit (raspberries I think).
Which molecules carry genetic information from one generation to the next?
They are DNA molecules. They are stored in chromosomes
Would a male with Down syndrome and a male without Down syndrome have a child with Down syndrome?
== == * I did some research and learned that men with Down syndrome are usually sterile. Most women can get pregnant and have children. Since there is a high risk of Down syndrome in the baby (35%-50%), many times the pregnancy would end in a miscarriage. But many Down syndrome people have had children.
* Technically yes, but it's unlikely. Fertility is greatly reduced in both males and females with Down syndrome, although there have been a few cases of males fathering children and females bearing them.
* Actually, there has only been 1 case of a male fathering a child. A women with Down syndrome can have children, but there is a 50% chance that the baby will be born with Down syndrome.

What causes genetic variation in a species?
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
Some scientists reckon that in endangered species it is essential to clone in order to keep the species alive. However, cloning can cause difficulties, as if two of the same cloned animal mate, they can cause serious defaults in their young; such as missing legs! This however, does not make it essential and without further research it makes it unrealistic to clone any animals in case of incidents further down the line.
The genetic code is universal but what does this mean?
this means that the same genetic code that is used in humans is used in all other types of organisms as well. anything from animals to plants to bacteria uses the same system of triplet nucleotide bases (codons) to code for a single amino acid when building a polypeptide. remember that the genetic code is also degenerate- each codon only codes for one amino acid, but there can be several different codons that call for the same amino acid.
Should you continue to use genetic engineering?
no you may not even get the results you asked for. the cost is tremendous anyway, the cost may even be the child's life why risk that. take the chance of having a child naturally and save the risks and chances later.
Are farm crops getting more resistant to insects disease and other pests?
Yes and no. More resistance is being both bred and engineered into crops all the time. However, the germplasm pool for the major crop classes such as corn, soybeans and wheat is shrinking all the time which leaves the worldwide supplies at more risk should a disease or insect adapt to existing varieties. This is why plant breeders are frequently trying to find new "landraces" (old original plant forms) of crops to breed into existing germplasm to create more varied resistance.
No list cannot answer but Gregor Mendel is a possible answer. There are many people in the history of genetics
Do Hershey products contain genetic engineering?
Due to pressure from some anti-GMO groups Hersheys has begun transitioning the ingredients in its products to use less and less GMO and hormone augmented products such as getting away from using milk from cows that have been treated with growth hormones to stimulate milk production and switching from high-fructose corn syrup back to simple sucrose sugars. The biggest push has been in products intended for the European market which has overwhelming phobias about anything that might be GMO related even when there is no evidence of harmful effects (and in a few cases actual significant evidence of significant benefits). Some of the changes will definitely result in more healthy products - others are nothing but hype.
Relate the use of genetic engineering to the treatment of human illness such as hemophilia?
Many genetically engineered proteins are used to treat illnesses. For example, factor
VIII, a protein that promotes blood clotting, is now made by genetic engineering and sold
as a drug to hemophiliacs. Genetic engineers are also attempting to replace defective
human genes with healthy ones.
