What are the difference between a trait and a characteristic give one example of each?
A trait is a distinguishing quality or characteristic that is passed down genetically, while a characteristic is an observable feature of an organism. For example, eye color is a trait that can be inherited, while having freckles is a characteristic that can vary among individuals.
How are crops genetically modified?
They are genetically modified by controlling which ones reproduce. It is like a forced natural selection that is done by man in order to have desirable properties, like resistance to pesticides and herbicides.
Why do scientists create genetically modified crops?
Genetically modified crops are made in order to make a desired trait, such as high yield, disease resistance, large fruit etc. more pronounced and/or undesired traits, such as toxins and large seeds...
When is the only time a recessive trait appears on a organism?
A recessive trait only appears in an organism when it is homozygous for that trait, meaning it has two copies of the recessive allele. This occurs when an organism inherits the recessive allele from both parents.
What is an organism with 2 alleles for 1 trait that are different?
The answer to your question, "What is an organism with 2 of the same alleles for a trait called?" is homozygous. it is just homozygous-By SciienceFreak
Can a modified trait in an organism be undone?
no
What caused genetically modified foods to happen?
Genetically modified foods happened because man discovered that a gene could be removed from one species and forced into the cells of another species to bring about a desired trait in the host, or that a gene could be removed from an organism, modified in some way, and inserted back into the same organism. In the most common genetically modified foods today (2015), the desired trait is either resistance to a herbicide or to produce an insecticide in the plant itself, although there are some other, less common traits produced through genetic modification.
What does it mean when a food product is genetically modified?
If a food product is genetically modified, it means that it is the product of an organism (such as a plant) which has had its DNA changed. This includes techniques such as inserting a gene into an organism's DNA so that it will have a new trait. For example, some corn crops have had a gene inserted into their DNA which makes them more resistant to herbicides and insect pests. Genetic modification can be seen as 'unnatural' and therefore some people choose not to eat GM foods.
What role does technology play in genetically modified food?
Without technology, there would be no genetically modified foods, because the technology to remove a gene or genes from one species and insert it into another to produce a desired trait would not be available.
How are foods genetically modified?
Generally, foods are genetically modified by taking a gene from one species and forcing into the cells of another species in a lab to produce a desired trait. This differs from hybridization in that it is transgenic (between species) and the gene is physically forced into the cells.
What is meant by traits?
An acquired trait is a characteristic of an organism that developed after the organism began life. For instance, a limp from a broken leg is an acquired trait. In contrast, an innate trait is one that an organism had (or was genetically determined to develop) at the time the organism began life. An example of this would be a cat being born with a tabby-stripe coat pattern.
What is genetically modified food and how is this process achieved?
Genetically modified foods are those that have been genetically engineered to insert a gene from one species (often a bacteria) into another species (corn, soy, etc). This is accomplished by cutting a target gene that will produce a desired trait from one species and artificially inserting it into the target plant.
A genetically determined characteristic?
Trait
What is a synonym for inherited trait?
Genetically acquired trait.
What is meant by acquired trait?
An acquired trait is a characteristic of an organism that developed after the organism began life. For instance, a limp from a broken leg is an acquired trait. In contrast, an innate trait is one that an organism had (or was genetically determined to develop) at the time the organism began life. An example of this would be a cat being born with a tabby-stripe coat pattern.
What are drugs in genetically modified food?
Except for the rBGH hormone used in animals raised for food, genetically engineered food does not actually contain drugs. Genetically modified foods involve extracting a gene from one species (often a bacteria) and inserting it into another species (often corn or soybeans) in order to bring about a desired trait. This process is also used to develop new drugs
What is genetic modified foods?
Genetically modified food can also be achieved by altering their DNA (or genes) by genetic engineering techniques. This usually involves inserting a gene into the organisms' DNA to create a certain trait. For example, some corn crops have been genetically modified so that they become more resistant to herbicides and insect pests. In most countries Genetically Modified foods (GM) as well as foods containing GM source foods have to be labelled by law, giving consumers the choice to use them or not. Agriculturally speaking the opposite of GM foods are "Organic" crops.
