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.
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
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.
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
Dominant genes will cover up recessive genes. Take a simplified version of eye color for example. Brown is dominant and blue is recessive. Someone might have the allele for both brown and blue, but their eyes will be brown because of the dominent brown gene. If there are two parents that carry the recessive gene, neither will be blue eyed, but they will have a chance of having a blue eyed child if both pass on the recessive gene.
Incomplete dominant alleles.
The dominant genes take over, and then the recessive genes hide away
Actually a chromosome consists of many genes/alleles and is neither recessive or dominant in and of itself.
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
Schizophrenia is only partially genetic, and therefore is neither recessive nor dominant.

Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
