How many recessive alleles are needed to be expressed?
Depends on the characteristic. Assuming you're talking about a very simple monogenic characteristic (ie. a characteristic which is dependent on one gene only) your dominant allele will always trump your recessive allele. So, one copy of your dominant allele is all that's needed to give you that characteristic (final genotype is either homozygous dominant or heterozygous), whereas you'd need two copies of your recessive allele (homozygous recessive) to get that characteristic. Much beyond that and it gets verycomplicated.
Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
How can alleles be?
Alleles can either be recessive or dominant. Dominant alleles produce a dominant trait which is normally seen, whereas although the recessive allele is present, the recessive trait is not normally visible. However, in cases of codominance and complete dominance the dominant trait does not completely hide the recessive trait and it can show through.
Is chromosomal mutation dominant or recessive?
They can be both. Wikipedia provides small descriptions of some of the different types of mutation
If an offspring receives a pair of trait-controllers containing both a dominant and a recessive trait what happens to the recessive trait?
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
What are the causes of PXE?
PXE is caused by changes in the genetic material, called mutations, that are inherited in either a dominant or recessive mode.
What is the phenotype of a purebred recessive?
A recessive trait is known as the characteristic that is the outward expression of the gene. Recessive traits can be masked by dominant traits but are still present if the gene is present in the organism.

What are the different forms of a gene either dominant or recessive?
heterozygous, homozygous dominant or homozygous recessive
An allele is either what or what?
Dominant or recessive

Would a mutation be a dominate or a recessive trait?
A mutation can be either recessive or dominant depending on what trait it is.

What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
Are sex linked traits dominant or recessive?
They can be either or depending on the trait.
