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.
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.
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
Schizophrenia is only partially genetic, and therefore is neither recessive nor dominant.
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
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 trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
The form of a trait that appears to mask another form of the same trait is called the dominant trait. Dominant traits will be expressed over recessive traits in a heterozygous individual.
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
The trait of raising one eyebrow is considered to be a dominant trait.
recessive
A dominant trait will appear in offspring that inherits at least one copy of the dominant allele from either parent. If an individual has two different alleles for a trait (one dominant and one recessive), the dominant trait will be expressed.
