The genetic makeup of an organism at fertilization determines only the organism's potential to develop and function.

How can internal environment of an organism affect gene function?
The internal environment of an organism can affect gene function by influencing factors such as hormone levels, nutrient availability, and stress response pathways. Changes in these internal conditions can trigger alterations in gene expression, leading to different cellular responses and potentially impacting the overall functioning of the organism.
How can a mutation in a gene affect the trait that an organism has?
A mutation in a gene can alter the functioning of the protein it codes for, leading to changes in the trait expressed by the organism. This can result in new traits, loss of function, or altered function of the protein, impacting the organism's phenotype.
What is the primary function of a gene in an organism's genetic makeup?
The primary function of a gene in an organism's genetic makeup is to provide instructions for making specific proteins that are essential for the organism's growth, development, and overall functioning.
How can a mutation in gene affect the traits that an organism has?
The gene will code for a different protein than it should.
How can a mutation in a gene affect the traits that an organism has'?
The gene will code for a different protein than it should.
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.
Can An insertion of a DNA base into a gene can affect an organism?
Yes, the insertion of a DNA base into a gene can significantly affect an organism. This change can alter the amino acid sequence of the resulting protein, potentially impacting its function. Depending on the nature of the insertion, it may lead to a nonfunctional protein, a gain of function, or even cause diseases. In some cases, such mutations can also contribute to evolutionary adaptations.

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.
