A person who has one dominant and one recessive copy of a gene is termed a "heterozygote." This means they have two different alleles for that gene, with one being dominant and the other recessive.
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.
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.
its different because adominant allele is in charge
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.

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).
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.
Dominant and recessive are terms used to describe how a particular allele (gene variant) is expressed in an individual's phenotype. A dominant allele will be expressed even if only one copy is present, while a recessive allele needs two copies to be expressed. Dominant traits mask the expression of recessive traits in an organism.
its different because adominant allele is in charge
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.
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.
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.
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.
