The gene responsible for it can be transmitted from generation to generation and each child born to someone with the gene has a 50:50 chance of receiving the gene and manifesting the disease.

This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. A mutation in a transcription factor that removes the activation domain, but still contains the DNA binding domain.

Consciousness can be defined by behavior or by electrical pattern of brain activity. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes). Definition noun (general) The state of being dominant; supremacy (genetics) The property of a gene (or allele) when it suppresses the expression, or dominates the effects, of the recessive gene (or allele). In ecology, dominance pertains to the high status of an organism or a group of organism in a social group. dominant - an allele that produces the same phenotype whether its paired allele is identical or different It is not intended to provide medical, legal, or any other professional advice.

A gene or allele shows dominance when it suppresses the expression, or dominates the effects, of the recessive gene (or allele).

Dominant means to be in control. Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. Thus, it would have a greater access to limited resources, such as food, mate, and space.
