What is incomplete penetrance?

Referring to the presence of a gene that is not phenotypically expressed in all members of a family with the gene.


Which occurrence is when an individual inherits a dominant gene but does not fully express the dominant phenotype?

Incomplete penetrance


How penetrance and expressivity can affect phenotypes?

Penetrance refers to the proportion of individuals with a specific genotype that actually express the associated phenotype, while expressivity describes the variation in phenotype expression among individuals with the same genotype. High penetrance means most individuals with the genotype show the phenotype, whereas low penetrance results in some individuals not expressing it at all. Expressivity affects how intensely or in what form a phenotype appears, leading to a spectrum of manifestations even among those with the same genetic background. Together, these factors can lead to diverse phenotypic outcomes in a population, complicating the prediction of traits based on genotypes alone.

How were Drosophila used to explain basic aspects of pattern formation axis formation and segmentation?

A study of generally uniform line of Drosophila flies shows that when moisture content is high during development, more flies in the population develop abnormal abdominal phenotype. Therefore greater percent of penetrance is observed with increased moisture. The reverse is the case if the moisture content is low. Penetrance is the frequency of phenotypic expression of a gene or allele in a family.


Will every individual who inherits the allele for Huntington's disease develop the disease?

Yes, Huntington's disease is autosomal dominant with high penetrance. Every individual who inherits the allele gets the disease.


Is Rett syndrome dominant or recessive?

Rett syndrome is a rare genetic disorder that is typically caused by a mutation in the MECP2 gene located on the X chromosome. It is not classified as dominant or recessive in the traditional sense because it primarily affects individuals with two X chromosomes. It is considered an X-linked dominant disorder with variable expressivity and reduced penetrance.


What is the prognosis for Machado-Joseph disease?

Machado-Joseph disease presents a 94.5% penetrance, which means that 94.5% of the mutation carriers will develop the symptoms during their lives, and less than 5% will remain free of symptoms
