What it the easiest way to determine if an organism is heterozygous or homozygous for a particular gene if self fertalization is not possible?
The easiest way to determine if an organism is heterozygous or homozygous for a particular gene, when self-fertilization is not possible, is through a test cross. This involves crossing the organism with a known homozygous recessive individual for the gene in question. If any offspring display the dominant phenotype, the organism is heterozygous; if all offspring show the dominant phenotype, then the organism is homozygous dominant. This method allows for clear observation of the genetic makeup based on the phenotypic ratios of the offspring.
A transgenic organism that has extra copies of a gene produces more of RNA the that is coded for by the gene?
In a transgenic organism with extra gene copies, there is typically an increase in the production of the corresponding RNA due to the additional gene copies being transcribed. This can lead to an elevated expression level of the gene's product, which could result in observable phenotypic changes in the organism.
Thought Out what process gene from one organism can be combined with a gene from another organism?
The process of combining genes from different organisms is known as genetic engineering. This involves isolating the desired gene from one organism, modifying it if necessary, and then inserting it into the genome of another organism. This can be achieved through techniques such as gene cloning, PCR, and gene editing tools like CRISPR.
What is meant by gene knockout testing?
Gene knockout testing is a technique used to study the function of a specific gene by inactivating or "knocking out" the gene from an organism's genome. This is typically achieved through genetic engineering methods such as CRISPR-Cas9 to create organisms that lack the target gene. By observing the effects of the gene knockout on the organism, researchers can learn more about the gene's normal function and its role in biological processes.
What is functional complementation?
Functional complementation is a genetic technique used to identify a gene by introducing a mutant organism with a defective gene to see if another organism with a functional copy of that gene can rescue the mutant phenotype. If the introduced gene can restore the normal function, it indicates that the gene is responsible for the observed phenotype in the mutant organism.
Is it possible to have a heterozygous recessive organism that displays the recessive gene?
that is what im figuring out, sorry :(
What does a gene do in a organism?
A gene has all the traits of the organism

What is the term for when two or more versions of a gene are present in an organism?
The term for when two or more versions of a gene are present in an organism is called "gene polymorphism."
What gmo or non gmo mean?
A non-GMO is an organism that has not been altered in a lab with a gene from an unrelated organism, such as corn that has been altered with a gene from a bacteria.

What is an organism with one dominant and one recessive gene for a trait?
An organism with one dominant and one recessive gene for a trait is called a heterozygote. In this case, the dominant gene will be expressed in the organism's phenotype, while the recessive gene will not be expressed unless the organism inherits two copies of the recessive gene.
What is functional complementation?
Functional complementation is a genetic technique used to identify a gene by introducing a mutant organism with a defective gene to see if another organism with a functional copy of that gene can rescue the mutant phenotype.
