A person who has one dominant and one recessive copy of a disease gene is typically considered to be affected by the condition if the disease is caused by the dominant allele. In this case, the dominant allele's effects will manifest, overshadowing the recessive allele. The individual may not express traits associated with the recessive allele, as the dominant trait takes precedence.

What do you call a person who has one dominant and one recessive copy of a gene?
We call a gene that has two different alleles heterozygous.
What is the genotype of a person who is a carrier of a autosomal recessive trait?
The genotype of a person who is a carrier of an autosomal recessive trait is typically heterozygous, meaning they carry one copy of the recessive allele and one copy of the dominant allele for that trait. This would be represented as Aa, with the lowercase "a" representing the recessive allele.
Is widows peak a dominant or recessive trait?
Widow's peak is a dominant trait. This means that if a person inherits one copy of the gene for a widow's peak from either parent, they will have a widow's peak.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
Why can a person have one copy of the CF allele and be perfectly normal?
CF is recessive, and as such, the gene for non-CF is dominant over this gene. The CF gene will only be expressed in the phenotype and as a characteristic if the person has two of the recessive alleles.
What is an organism that has a dominant and a recessive copy of a gene?
dogs have a dominant and a recessive copy of a gene

. Is a person who is homozygous recessive for a recessive genetic disease a carrier?
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
Is widows peak a dominant or recessive trait?
Widow's peak is a dominant trait. This means that if a person inherits one copy of the gene for a widow's peak from either parent, they will have a widow's peak.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
Why can a person have one copy of the CF allele and be perfectly normal?
CF is recessive, and as such, the gene for non-CF is dominant over this gene. The CF gene will only be expressed in the phenotype and as a characteristic if the person has two of the recessive alleles.
Is it possible to have a dominate recessive trait?
no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
Is a disorder know as a dominant or recessive?
A disorder can be either dominant or recessive, depending on the specific genetic inheritance pattern. Dominant disorders only require one copy of the mutated gene to be expressed, while recessive disorders require two copies.
Is thalassemia a dominant trait?
No, thalassemia is not a dominant trait; it is inherited in an autosomal recessive manner. This means that a person must inherit two copies of the mutated gene, one from each parent, to exhibit the disease. Individuals with only one copy of the mutated gene are carriers and typically do not show symptoms.
