What result will occur when a new allele enters the gene pool?
Esanchez
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

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.
Alternative versions of a gene?
One or more forms of a gene that codes for a specific trait is also known as an allele
Different forms of a gene?
the alternative form of a gene is called an "allele."
What are gene pairs called?
Allele
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What would occur as a result of changes in the frequency of a gene?
Change in the frequency of an allele, to be pedantically precise. Answer; evolution.
What is a alternate forms of a particular gene called and they rise as a result of what?
Allele
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 when of allele is the number of times that the allele occurs in a gene pool compared with the number of times other alleles occur?

Allele in gene or gene in allele?
Alleles are the specific form of a gene e.g. gene for 'eye colour, allele for 'blue eyes'. Therefore the alleles are in the genes.
What is the alternate form of a gene?
The answer is allele
Alternative versions of a gene?
One or more forms of a gene that codes for a specific trait is also known as an allele
What is a different between allele and gene?
an allele is a gene that is the cause of hereditary variation
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.
What is member of a gene pair that determines a specific trait is?
an allele
