What is a person who has a dominant and one recessive copy of a disease gene?
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 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
Why do we call some alleles dominant?
because it dominates the phenotype
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.
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).
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
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.
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 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.
Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
How is Dominant and Recessive differ?
Dominant traits are expressed when just one copy of the gene is present, while recessive traits require two copies to be expressed. Dominant traits mask recessive traits when they are both present.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes 8 copies of a recessive gene to overpeower dominant gene
