Dominant alleles carry traits or characteristics that will show no matter what.
Recessive alleles carry traits where you must be homozygous for the recessive trait in order for it to show.
Dominant alleles are represented by capital letters (EX: R or M)
Recessive alleles are represented by lower case letters (EX: r or m)
In order for a dominant allele to show, you can have either RR or Rr, since it is dominant.
However, in order for a recessive allele to show, you MUST have rr.
Hope this helps!
False, neither allele is dominant over the other. This is called incomplete dominance.
Dominant alleles will show their effect whether there are one or two alleles present in the genotype.
True
Dominant
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.
The physical trait exhibited by an organism's genes is called the phenotype. (As opposed to the genotype, which refers to the alleles themselves.)
The outward appearance is usually called the phenotype. In contrast the alleles present in the cells is called the genotype.
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
When genes are expressed, the result is called phenotype. What is actually in all the genes (some are recessive) is called the genotype.

No. Genotype is the combination of genes present in an organism. It consists of alleles whose visible characteristics is called phenotype. An organism's phenotype is visible and not the genotype as you just can't see a person and tell what kind of genes are present in the organism.
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.
you mean phenotype, and its dominant alleles
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
Different, such as Bb.
When genes are expressed, the result is called phenotype. What is actually in all the genes (some are recessive) is called the genotype.
Phenotype
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
