Recessive gene alleles are ones for which two copies are required to cause disease. Many people may have one copy and be phenotypically normal (non-diseased). People who have the disease will have gotten one copy from each parent, each of whom may be normal unless they, themselves have two copies.

Is Canavan disease inherited?
Yes, Canavan disease is an inherited genetic disorder caused by mutations in the ASPA gene. It is inherited in an autosomal recessive pattern, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.
If a boy inherits a disease that is autosomal recessive he inherited it from his mother?
If a boy inherits an autosomal recessive disease, he would have inherited one copy of the mutated gene from each of his parents. The mother is a carrier, meaning she has one copy of the mutated gene but does not show symptoms of the disease. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and have the disease.
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.
If a daughter expresses an x-linked recessive gene she inherited the trait from?
If a daughter expresses an X-linked recessive gene, she inherited the trait from her father who carries the gene on his X chromosome. Since males only have one X chromosome, if they have the gene, daughters will always inherit it from their father.
Many serious diseases can be passed from parent to offspring through genes. In which case given below is a recessive disease NOT able to be passed on?
A recessive disease is not able to be passed on if both parents are carriers of the gene but do not express the disease themselves. In this case, the offspring would only inherit the disease if they receive two copies of the recessive gene, one from each parent. If the child inherits only one recessive gene and one dominant gene, they will be a carrier but will not exhibit the disease. Thus, the disease can only be passed on if both parents contribute the recessive allele.
Is Canavan disease inherited?
Yes, Canavan disease is an inherited genetic disorder caused by mutations in the ASPA gene. It is inherited in an autosomal recessive pattern, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.
What is an inherited eventually fatal disease of the exocrine cells that is carried by a recessive gene?
cystic fibrosis
Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
If a boy inherits a disease that is autosomal recessive he inherited it from his mother?
If a boy inherits an autosomal recessive disease, he would have inherited one copy of the mutated gene from each of his parents. The mother is a carrier, meaning she has one copy of the mutated gene but does not show symptoms of the disease. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and have the disease.
What is meaning of recessive traits?
an inherited character determined by a recessive gene
What is a disease caused by an inherited abnormal gene?
Recessive diseases are severe and may lead to an early death. They include sickle cell anemia.Tay-Sachs disease.cystic fibrosis.phenylketonuria (PKU).
Is Stickler Syndrome a dominant gene or a recessive gene?
Most commonly is caused by a mutation in one of three types of collagen genes - COL2A1, COL11A1, COL11A2 and is a dominantly inherited disease. A recessive type has also beed described with a mutation in the COL9A1 gene.
Is inherited from only one parent the offspring Will have that genetic?
Recessive 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.
2 A child is diagnosed with a rare genetic disease Neither parent has the disease How might the child have inherited the disorder?
Both parents are carriers of the recessive gene and if the child inherits that gene from both mother and father the child will have the disease even though the parents don't.
What form of Niemann Pick can be inherited?
All forms of NPD are inherited autosomal recessive disorders, requiring the presence of an inherited genetic mutation in only one copy of the gene responsible for the disease. Both males and females are affected equally.
What example describes an inherited trait that cannot be determined by observing an individual?
A genetic trait that is inherited but not visually expressed, such as a recessive gene for a disease or a carrier status, cannot be determined by observing an individual without genetic testing. For example, an individual who carries a recessive gene for a genetic disorder may not show any symptoms themselves, but can pass on the gene to their offspring.
