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
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.
Dominant, as in dominant and recessive (weaker) genes.
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.
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.
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.

Schizophrenia is only partially genetic, and therefore is neither recessive nor dominant.
