What type of alleles are present in an organism?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
Combinations of alleles are know as a genotype?
Genotype is the set of all genes present in the nucleus of a somatic cell. Alleles are segments of DNA containing multiple genes
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.
When will a trait controlled by a recessive allele be shown?
only when two recessive alleles are present
What are the particular genes present in an indivial called?
Genotype
A hetrozygous genotype is when the alleles present are?
Different, such as Bb.
Which allele is expressed even if only one copy is present in genotype?
dominant alleles
What type allele are present in an organism with a QQ genotype?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.

A heterozygous genotype is when the alleles present are such as Bb?
different, not alike, homozygous is alike
The detectable traits of an organism as determined by what alleles are present is the what?
The physical trait exhibited by an organism's genes is called the phenotype. (As opposed to the genotype, which refers to the alleles themselves.)
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.

What is the outward appearance in inheritance?
The outward appearance is usually called the phenotype. In contrast the alleles present in the cells is called the genotype.
When will a trait controlled by a recessive allele be shown?
only when two recessive alleles are present
What is a term used to express the actual DNA make up of a gene?
Genotype: Genetic makeup of an individual ( the alleles present in an individual)
