Instead of having only two alleles for a trait, there are more than two. An example in humans is the ABO blood group system, where there are three alleles that are possible. However, an individual can only inherit the alleles of his/her parents, for a total of two alleles.

Gene interactions in which an allele at one locus prevents the expression of an allele at another locus is called?
This is called epistasis.
What Does a particular trait result from the expression of a single gene?
Huntington's disease is a perfect example of a single gene trait. A mutation in this allele causes Huntington's disease in later life. A dominant trait. Widows peak us another. Any gene that controls the total expression of a trait is an allele defined as a single gene trait.
What allele covers up or dominates the other trait?
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product.
What gene pair is made up of one dominant allele and one ressecive allele?
A heterozygous condition resulting in the dominant genes expression in the phenotype.
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.
Gene interactions in which an allele at one locus prevents the expression of an allele at another locus is called?
This is called epistasis.
What is the capacity of one allele to suppress the expression of a contrastingly recessive gene?
dominance
Capacity of one allele to suppress the expression of contrasting recessive gene?
dominance
What is an allele whose trait always shows up in the organism?
type 2 Diabetes
ABO blood group expression is an example of?
multiple allele inheritance.
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
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.
