When the alleles present for a trait are the same, it is called Homozygous
you mean phenotype, and its dominant alleles
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
There are two cases where this can happen: Case 1: Codominance: Both alleles are equally present but are distinct. a good example of this is when you breed a white cow with a red cow. both white and red are dominant. when you look at the offspring, it is roan; it has both white and red hairs mixed in with each other. Case 2: incomplete dominance: Both alleles are equally present but are not distinct. a good example of this is is when you mix a white flower and a red flower and you get a pink flower
only when two recessive alleles are present

A trait is generally expressed phenotypically. An allele is one of a pair alleles at the same locus...often referred to as a gene. An allele is present whether expressed or not. A single gene locus will have two alleles in an individual, but there may be more than 2 alleles for this locus in the population. General human blood groups are an example of this with A,B, O as the primary alleles and several other less common ones...(like M) present in the population.
No. They are present but not expressed (seen). Only the dominant alleles are expressed.
An allele present in all members of a population
When the alleles present for a trait are the same, it is called Homozygous
A cell is said to be homozygous for a particular gene when identical alleles of the gene are present on both homologous chromosomes. For example, if the alleles are AA or aa the cell is homologous for that trait. It is heterozygous if it is Aa
