No, it doesn't necessarily occur just because it's present in the family. There are more factors involved in schizophrenia than a specific gene. Other mental/emotional symptoms may exist in the family because of the presence of a genetic type but full blown schizophrenia is unlikely.
It is called a dominant trait
A trait that masks another trait is called dominant, or a dominant trait.
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
The trait that is being masked is recessive, and the trait that is doing the masking is dominant.
Schizophrenia is only partially genetic, and therefore is neither recessive nor dominant.
A trait that masks another trait is called a dominant trait. This means that when an organism carries both dominant and recessive alleles for a particular gene, only the dominant trait will be expressed in the phenotype.
A dominant trait.
Dominant Trait
Dominant- Covers up another form of a trait. Recessive- Is covered up by a dominant trait.
the dominant trait
The recessive trait isn't present when the dominant form of the trait is there. Whenever a trait is dominant trait is present it ALWAYS takes over the recessive one. the law of Dominance
In genetics, a trait is considered dominant when it determines a phenotype over a recessive trait. For example, AA is crossed with AA to make Aa, Aa, Aa, and Aa. If "A" is the dominant trait and "a" is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype. A dominant trait is just how it sounds, it dominates over recessive traits when they are both present.
