There's not exactly a clear-cut way to answer this.
If someone is homozygous dominant, that means they have two dominant genes, AA for example, and, of course, the dominant phenotype (phenotype just means the physical expression of a trait/gene) will be expressed.
If someone is homozygous recessive, meaning they have two recessive genes, aa, they would then express the recessive gene.
Now, in cases of complete dominance and a person with a heterozygous genotype (Aa), the dominant gene will always show itself, which is probably the answer you were looking for.
Be careful not to generalize too much, it's an easy way to get tripped up on tests.

What principle does a person with AB blood illustrate?
a person with AB blood group exhibits a genetic principle called "co-dominance" Explanation there are three genes responsible for the four human blood groups i.e. A, B, O and AB. the genes are Ia, Iband Io. Ia and Ib are dominant genes while Iois a recessive gene. if a person has the genotype IaIa or IaIo he/she will exhibit the blood group "A" similarly a person with genotype IbIb or IbIo will show the blood group "B". But a person with genotype IoIo will show the blood group "O"( IoIo is a homozygousrecessive condition ) since Ia and Ib are dominant genes they express themselves in both homozygous dominant (IaIa and IbIb) condition and heterozygous dominant(IaIo and IbIo) condition. but when the genotype of a person becomes IaIb neither of Ia or Ib genes is able to dominate the other. This is when the principle called "co-dominance" is observed in which both the genes Ia and Ib express themselves to give rise to "AB" blood group.hope i could provide a satisfactory answer ! good luck !!
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
Explain the difference between a polygenic character and a complex character?
the difference is that a polygenic character is is influenced by several genes and they show many variation, complex characters are influences strongly the environment and genes.
Who can get dwarfism?
Anybody if its in their genes......... Like the show the little couple lol
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
The combination of genes in which a mixture of both traits show is called what?
Heterogeneous is when offspring inherits mixed genes from both parents.
What does punnett squaremean in biology?
show the genes put togetheir to show off spring genes
Where is evolution headed?
Evolution has no destination. New mutations show up every generation. Unsuccessful genes die out every generation. Successful genes multiply every generation. The environment is always changing, therefore the criteria for which genes are successful is always changing. The rise one one new gene, or the loss of a gene, can itself increase or decrease the value of other genes.
How do you deal with one who considers themselves always correct on any subject?
try to show them your opinion.
How does DNA show relationships between organisms?
it shows genes and different genes
Why are genes called dominent?
Each gene has two alleles. When an allele is dominant, it will express the phenotype of that allele. Recessive alleles are only expressed when there are two copies of that allele. Edited answer: Only those genes are called dominant which show their phenotypic expression in an individual.

Is it true that all genes show simple patterns of dominant and recessive allleles?
No, it is not true that all genes show simple patterns of dominant and recessive alleles. When Mendel did his studies on peas, he was lucky in that the genes he worked with showed those patterns. Many genes are much more complex and often involve more than one gene. Many genes show intermediate expressions between dominant and recessive.
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
What is the connection between genes and alleles?
they both show something about appearance.
