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 is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
Allele that prevents the expression of a recessive allele?
A dominant allele
What is the difference between an inactive allele and an expressed allele?
The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
What is an allele that always shows up in an organism's phenotype called - an allele that masks the other allele?
The dominant 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 allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
Null Null Null?
Very small.
If null is compared with null what is the result-true or false or null or unknown?
You mean SQL? NULL = anything IS NULL NULL <> anything IS NULL ... NULL IS NULL = TRUE NULL IS NOT NULL = FALSE
What is the alternate form of a gene?
The answer is allele
How do you get to the null in supersecret?
There is no null, it is just what it says when you log out. There is a null.
An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
Allele that prevents the expression of a recessive allele?
A dominant allele
Can a recessive gene be hidden from a dominant?
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
What is the difference between an inactive allele and an expressed allele?
The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
