That depends on several factors. Many (as much as 1/3) new alleles are lost from populations within a few generations due to genetic drift, even if moderately selected for. If you think about the chances of one new allele making into a gamete that actually becomes a zygote (what if the organism with the one new allele never finds a mate, for example?), you can see the kind of hurdles the allele has to overcome in the first few generations. If the new allele is very strongly selected for, it may have a better chance of growing in frequency, but the majority of new alleles will probably be deleterious, and therefore removed by selection. Neutral alleles will have a greater probability of increasing in frequency in small populations, rather than large

Alternative versions of a gene?

Alternative versions of a gene are called alleles. Alleles are different forms of a gene that can result in distinct traits or characteristics. These variations in alleles contribute to genetic diversity within a population.


Is an allele bigger then a gene?

An allele is a gene. It is one form of a gene. For example, height in pea plants is controlled by one gene with two forms. A pea plant can be tall or short. There is a short allele and a tall allele for the gene governing height.


Is allele a gene?

yes an allele is a gene


What are the characteristics of the allele gene?

An allele is the opposite form of a gene. In some cases it can result in some differences such as pigmentation or eye color but usually the differences can't be seen.


What is a alternate forms of a particular gene called and they rise as a result of what?

Alternate forms of a gene are called alleles. These alleles arise as a result of mutations in the DNA sequence of the gene.


What is an allele and how is it best defined in the context of genetics?

An allele is a variant form of a gene that can result in different traits or characteristics in an organism. In the context of genetics, an allele is best defined as one of the possible versions of a gene that can be inherited from each parent.


What is the alternate form of a gene?

The answer is allele


What is null allele?

A null allele is a mutant copy of gene that completely lacks that gene's normal function. This can be the result of the complete absence of the gene product (protein, RNA) at the molecular level, or the expression of a non-functional gene product. At the Phenotypic level, a null allele is indistinguishable from a deletion of the entire locus.


What does an allele code for?

An allele is a specific form of a gene that codes for a particular trait or characteristic. Alleles can result in different variations of the trait, such as eye color or blood type, depending on which allele is inherited from each parent.


What is a different between allele and gene?

an allele is a gene that is the cause of hereditary variation
