Genotype is the set of all genes present in the nucleus of a somatic cell. Alleles are segments of DNA containing multiple genes
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.
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.
only when two recessive alleles are present
Different, such as Bb.
One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If there are two different alleles for a particular gene, the genotype is heterozygous. If there are two of the same alleles, the genotype is homozygous.
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
dominant alleles
Genevieve has the genotype, referring to the specific combination of alleles that she has for a particular gene. This genotype could dictate her physical characteristics or susceptibility to certain diseases based on the specific alleles present.

different, not alike, homozygous is alike
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.
Dominant alleles. Dominant alleles will always be expressed in the phenotype, even if only one copy is present in the genotype.
Genotype is more inclusive than allele. Genotype refers to the genetic makeup of an organism, including all alleles present at a particular genetic locus. Allele is a specific form of a gene that can be present at a given locus within an organism's genome.
Alleles are different versions of a gene that can code for different traits. The two forms of alleles are dominant and recessive. Dominant alleles mask the effects of recessive alleles when present together in an individual's genotype.
