genes can be codominant for example in blood groups a person can be A,B,AB or O. neither A nor B is more or less dominant than each other but they are dominant over O.
there are many other types of dominance/recessive relationships in genes. you could look up epistasis on wikipedia to get a better idea of the bigger picture.

What Happens when genes are neither recessive nor dominant?
When genes are neither recessive nor dominant, they are said to exhibit incomplete dominance or co-dominance. In incomplete dominance, both alleles are expressed in the phenotype, resulting in a blending of traits. In co-dominance, both alleles are fully expressed in the phenotype, leading to a combination of traits.
When a gene inherited from one parent masks the expression of the gene inherited from the other parent that gene is said to be?
That gene is said to be dominant. Dominant genes will be expressed over recessive genes in a heterozygous individual.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
Gene pairs consists of two dominant alleles or two recessive alleles?
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
The most powerful genes are said to be?
Genes that are considered to be powerful are usually those that code for essential cellular functions, such as those involved in regulating cell growth and division, controlling metabolism, and responding to external signals. These genes are often called "master regulators" because they have a broad impact on the cell's behavior and can influence multiple downstream pathways. Mutations in these genes can lead to significant changes in cell behavior and are often associated with diseases like cancer.
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
What Happens when genes are neither recessive nor dominant?

In incomplete dominance, both alleles are expressed in the phenotype, resulting in a blending of traits.

When a gene inherited from one parent masks the expression of the gene inherited from the other parent that gene is said to be?
That gene is said to be dominant. Dominant genes will be expressed over recessive genes in a heterozygous individual.
My children were born had a plus now mydaughter is pregnant and doctor said she is a - can this happen?
Odds are one of the tests were mixed up or done improperly. Have her get retested by her Dr to make sure. Also could the genes be a factor? + blood could be dominant, - recessive and the daughter could have had dominant and recessive genes for blood types, and her boyfriend could be recessive or dominant and recessive, so when their DNA mixed, the result could have been double recessive.?
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
An organism with two different alleles for a single trait is said to be heterozygous?
A heterozygous is a hybrid of genes. It has a dominant and recessive gene. The dominant gene covers over the recessive trait, making the individual have the dominant trait. (trait are alleles...) or apex ans:two
A person having two genes that are alike is said to be?
Homozygous. This means that both alleles for a particular gene are the same, either both dominant or both recessive.
What are the most powerful genes are said to be?
Dominant
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
If two genes in a gene pair are for the same trait what will that trait be?
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed.
