Is diabetes type 1 dominate or recessive trait?

Is diabetes type 1 dominate or recessive trait?

Neither: The tendency toward this disorder is influenced by heredity but not transmitted as a dominant or recessive. It falls into a category called "multifactorial" in which the genes in several different locations & possibly several chromosomes may come into play.Many conditions with about 5% inheritance risk fall into this category. ...Read more

What are dominant vs recessive gene diseases?

See below: With a dominant gene trait, the child only needs to receive one copy of the abnormal gene. So, they have a 50% chance of getting the gene. With a recessive gene, the child needs 2 copies of the gene. So, they have a 25% chance of having both genes. ...Read more

What is recessive vs dominant heredity?

Mendellian genetics: In mendellian genetics, you inherit half your genes from your mom & half from your dad. Each of these genes can then be either recessive or dominant. Dominant genes only require one copy from either mom or dad to make trait apparent. Recessive genes require one copy from both mom & dad to make trait apparent. Carrier is person w/one copy of recessive gene (from either mom or dad). ...Read more

How does the dystrophin gene which causes becker type muscular dystrophy get mutated ?

How does the dystrophin gene which causes becker type muscular dystrophy get mutated ?

2 ways: Genetic information is passed down from parents to their child, either accurately, or with random changes called "spontaneous" mutations. Muscular dystrophy can be inheirited, or occur for the first time in an individual. The actual number of dystrophin "copies" made by the gene of the individual can vary. Environmental factors are not suspected at this time. ...Read more

Is sickle cell dominant or recessive in its inheritance?

Is sickle cell dominant or recessive in its inheritance?

Recessive: Sickle cell is autosomal recessive which means both parents must have a copy of the defective allele (one or both can be carriers but exhibit no symptoms). ...Read more

Hello docs, is achondroplasia dominant or recessive?

Hello docs, is achondroplasia dominant or recessive?

What is the difference between autosomal dominant and autosomal recessive inheritance?

What is the difference between autosomal dominant and autosomal recessive inheritance?

2 copies of genes: We all have two copies of each gene in our chromosomes. In autosomal dominant conditions you only need one copy of the gene to have the disease. In autosomal recessive conditions you need two copies in order to have the disease. It is called recessive because people with only one copy do not have the disease, that is the conditions recedes or is hidden. ...Read more

What is the medical definition of autosomal dominant and autosomal recessive?

What is the medical definition of autosomal dominant and autosomal recessive?

Input required: In dominant disorders, the dominant member of the gene pair controls how the gene activities are expressed, so the other gene can carry the same or normal information.In recessive disorders, the normal gene compensates for the bad information in the other gene, allowing a person to function normally unless both genes carry the bad information. ...Read more

Is edward's syndrome autosomal or sex-linked? Dominant or recessive?

Is edward's syndrome autosomal or sex-linked? Dominant or recessive?

None of the above: Edward syndrome is brought on by an abnormality of chromosome numbers, specifically an extra 18. The abnormal egg with a single chromosome 1-17 & 19-22 + x has a pair of 18's. When the sperm brings a single chromosome 1-22 + x or y then the embryo ends up with 47 chromosomes rather than 46 in every cell.(3-18's) the excess distorts the organ building information & defects arise. ...Read more

Is the beta-thalassemia gene recessive or dominant?

Neither: People normally have 2 beta globulin genes. A mutation in one or both genes leads to 3 levels of beta thalassemia. The genetics of the disorder is not all-or-none nor dominant-recessive. Instead, more or worse mutations causes worse disease. One mutation = beta thal trait (mild symptoms), 2 mutations = beta thal intermedia (transfusions sometimes) or beta thal major (lifelong transfusions needed). ...Read more

What type of inheritance for osteogenesis imperfecta?

What type of inheritance for osteogenesis imperfecta?

Autosomal dominant: Which means one copy of the altered gene in each cell is sufficient to cause the condition. And less comnnly autosomal recessive type of inhertance which means two copies of the gene in each cell are altered. The parents of a child with an autosomal recessive disorder typically are not affected, but each carry one copy of the altered gene. ...Read more
