An example of a homozygous recessive genetic disorder is the eye color. the dominant eye color is brown but a homozygous recessive genetic disorder it's haze;, blue, gray, etc.

Is hemophilia A inherited as a recessive or dominant trait?
Hemophilia A is inherited as a recessive trait.
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.
When two recessive alleles are inherited the trait is observed?
When two recessive alleles are inherited, the trait associated with those alleles is observed because there is no dominant allele to mask its expression. This results in the individual displaying the recessive trait.
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
What is an individual who has inherited a factor for a trait?
An individual who has inherited a factor for a trait is a carrier of that trait. They may or may not exhibit the trait themselves, as it depends on whether the inherited factor is dominant or recessive.
What are recessive genetic disorder?
When a genetic disorder is recessive, that means that two copies of the gene are necessary to have the trait or disorder. One is inherited from the mother, and one from the father. Disorders of this type include: cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.
What is the probability a woman heterozygous for an x-linked trait will have a son with a genetic disorder if the genetic disorder is recessive?
The probability would be 0.5 or 50%. A heterozygous woman will pass on the X chromosome with the recessive allele to 50% of her sons, and since the disorder is recessive, the son would only have the disorder if the X chromosome with the recessive allele is inherited from the mother.
Is hemophilia A inherited as a recessive or dominant trait?

Is disprexia a ressessive trait?
Dyspraxia is not a trait that is passed down in a simple Mendelian recessive or dominant manner like a genetic disorder. It is a complex neurodevelopmental disorder that can be influenced by a combination of genetic and environmental factors.
What type of trait is inherited of an organism receives two recessive alleles?
The trait received is recessive.
What type trait is inherited if an organism receives two recessive alleles?
The trait received is recessive.
Is spherocytosis of the liver hereditary?
In most cases spherocytosis is an inherited condition. It is caused by a genetic mutation that is considered a recessive trait.
When two recessive alleles are inherited the trait is observed?
When two recessive alleles are inherited, the trait associated with those alleles is observed because there is no dominant allele to mask its expression. This results in the individual displaying the recessive trait.
What type of traits is inherited if an organism receives recessive alleles?
The trait received is recessive.
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
