You are repeating yourself.
If a dominant gene inhibits reproduction, it will eventually work itself out of the population.
Whereas a recessive gene can sporadically pop up.
However, a gene such as a "cancer gene" might not inhibit reproduction, and thus could perpetuate at a higher rate in either a dominant or recessive form.
There is a theory called "Heterozygote Advantage" that certain genetic disorders such as Cystic Fibrosis or Sickle Cell Anemia may actually provide a protective advantage when found as a heterozygote recessive, but is deadly when the person inherits both genes.

How come there are no carriers in genetic diseases caused by dominant alleles?
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.
What kind of genetic disease is blindness?
It's hard to say, because blindness is caused by a thousand different things both environmental and genetic.

Huntington disease
What movement disorders are caused by inherited genetic defects.?
Some movement disorders, including Huntington's disease and inherited ataxias, are caused by inherited genetic defects
What is the genetic disease caused by maternal nondisjunction of autosome 21?

What term describes the inheritence cystic fibrosis?
The term that best describes the inheritance of cystic fibrosis is that it is genetic. Cystic fibrosis is caused by recessive alleles. Cystic fibrosis is an autosomal recessive genetic disease.
Is leprosy a genetic disease?
Known as Hansen's Disease, it is not genetic, but caused by an organism.
What term describes the inheritance if cystic fibrosis?
The term that best describes the inheritance of cystic fibrosis is that it is genetic. Cystic fibrosis is caused by recessive alleles. Cystic fibrosis is an autosomal recessive genetic disease.
Genetic disorders are caused by?
Genetic Disorders are caused By a change in a person's DNA. Recessive alleles is the most human genetic disorder.
What kind of genetic disease is blindness?
It's hard to say, because blindness is caused by a thousand different things both environmental and genetic.
Is influenza a genetic disease?
No, it's caused by a virus.
Is psoriasis caused by a pathogen?
No psoriasis is not caused by a virus or bacteria. It is a genetic disease.
What evidence is there that the long and round alleles did not become blended?
A number of genetic disorders are caused when an individual inherits two recessive alleles for a single-gene trait. Recessive genetic disorders include Albinism, Cystic Fibrosis, Galactosemia, Phenylketonuria (PKU), and Tay-Sachs Disease. Other disorders are also due to recessive alleles, but because the gene locus is located on the X chromosome, so that males have only one copy (that is, they are hemizygous), they are more frequent in males than in females.
What are genetic syndromes?
A genetic syndrome simply defined is: a disease caused by an abnormality in an individual's genetic make-up.
