When two of the same alleles are needed to be seen in the offspring's genotype those alleles are what?

Recessive alleles must be homozygous in order for the trait to be displayed phenotypically.

Can you determine a persons genotype based on phenotype?
In some cases but not others. Certain alleles can be dominant, which means that they will dictate the phenotype should there be a clash of alleles in the genotype. Other alleles can be recessive, which means you'd need both of these alleles in these genotype in order for it to dictate the phenotype. This means that if a person's phenotype represents a dominant trait, we cannot be certain what their genotype is. If, however, it represents a recessive trait, we know that their genotype must be the recessive allele twice.
What is an interaction between alleles in which both alleles are expressed more or less equally or a blending occurs called?
Those would be called co-dominant alleles.
What is the difference between a genotype and a phenotype?
Phenotype, This is the "outward, physical manifestation" of the organism Genotype, This is the "internally coded, inheritable information"
The genes that make each individual unique are?
The genes that make each individual unique are filed into a persons phenotype and genotype. These traits are different from those around them.
Identical alleles AAA or AAA?
Since they are capital letters they stand for a dominant allele. Both the letters stand for a different trait. This is saying these two different organisms were dominant in those specific traits.
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.

Complete Dominance
How do you find the possible genotypes of the children of a woman with blood type O and a man with blood type AB?
There are three alleles for blood type which can be represented by IA, IB, and i. A person with blood type O has the genotype ii. A person with blood type AB has genotype IAIB. If these two people produce children, those children will inherit one allele from each parent. They will therefore certainly inherit the i allele from their mother and either the IA or the IB from their father. The children with the genotype IAi will have type A blood, since the IA allele is dominant to the i allele. The children with the genotype IBi will have type B blood, since the IB allele is also dominant to the i allele.
How many of those offsprings would you expect to have white flowers?
That depends entirely on the proportion of white flowers in the parent population.
Why do you have more genotypes than phenotypes?
Because those alleles segregate, or seperate, and combine again to make different alleles, thus making different phenotypes.
