codominant alleles
Fabry's disease has an X-linked, recessive pattern of inheritance, meaning that the defective gene is carried on the X chromosome.
Wolman's disease is caused by a genetic defect (with a recessive pattern of inheritance) that results in deficiency of an enzyme that breaks down cholesterol.
Refsum's disease has a recessive pattern of inheritance and affects populations from Northern Europe, particularly Scandinavians most frequently.
Gaucher disease has a recessive pattern of inheritance, meaning that a person must inherit a copy of the defective gene from both parents in order to have the disease.
Its a pedigree. A pedigree shows the inheritance of a genetic disorder within a family and can help to determine the inheritance pattern and whether any particular individual has an allele for that disorder.
The inheritance pattern of the BRCA1 gene is dominant.
It has a recessive pattern of inheritance and is believed to occur in 1 of 40,000 births in the United States.
Hirschsprung's disease is typically non-Mendelian in inheritance, meaning it does not follow a simple dominant or recessive pattern. It is commonly associated with complex inheritance involving multiple genetic and environmental factors.
Gregor Johann Mendel is credited with discovering the pattern of genetic inheritance
A heterozygous individual who has one allele for a disease but is not affected by it is considered a carrier. Carriers can pass the disease allele to their offspring but do not exhibit the symptoms themselves. This is common in genetic disorders that follow a recessive inheritance pattern.
Tay-Sachs disease has a recessive pattern of inheritance, and approximately 1 in every 27 people of Jewish ancestry in the United States carries the TSD gene.
Types of dominance, multiple alleles, sex linked inheritance, polygenic inheritance and maternal inheritance.
