If an individual expresses a dominant disease will the children always inherit the disease?
Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.
IS Huntington's disease an autosomal recessive gene?
Nope. Dominant
Is Crohn's dominant?
The actual crohns "gene" (if there is one) has not yet been isolated. When it is, it will probably be found to be recessive. Many families with parents who have Crohns have children who do not have the disease and must go back several generations to find one who does. Studies are ongoing.
What are the chances a child will be born with a hereditary disorder or disease?
Depends on the disease- dominant gene or recessive gene- and the genotypes of the parents.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
Is cystic fibrosis carried on a dominant of recessive gene?
Cystic fibrosis is an autosomal recessive genetic disease.
What is an organism that has a dominant and a recessive copy of a gene?
dogs have a dominant and a recessive copy of a gene
Does FAP follow a recessive or dominant inheritance pattern and why?
FAP follows both an autosomal recessive and autosomal dominant pattern depending on which gene you inherit the disease from. If inherited through the APC gene, which is most common, it is autosomal gdthe disease. If inherited through the MUTYH gene it is autosomal recessive, meaning that both parents were carriers of the disease or they both were living with the disease.
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
What is an example of dominant inheritance?
Dominant Inheritance is when one parent has a dominant gene and the other has a recessive gene. The dominant gene overpowers the recessive gene, and only the dominant gene is phenotypically expressed.Source: http://www.accessexcellence.org/RC/VL/GG/recessive.phpSome examples are variegate porphyria, Huntington's disease and myotonic dystrophy.source: http://genome.wellcome.ac.uk/doc_WTD020849.html
A person who does not show a genetic disease such as Tay Sachs or Cystic Fibrosis but can pass the gene on to the next generation is called?
A carrier. This is usually a disease that requires two parts of a gene. The faulty gene is the recessive gene, and the healthy gene is the dominant gene. If two people with one dominant and one recessive gene each have a child they have a 25% chance of producing a child with two dominant genes, thereby resulting in that child having the disease.
