How can one determine whether a pedigree trait is dominant or recessive?
One can determine whether a pedigree trait is dominant or recessive by observing how the trait is passed down through generations. If the trait appears in every generation, it is likely dominant. If the trait skips generations, it is likely recessive. Genetic testing can also help confirm the inheritance pattern of the trait.
What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
How do you know from a pedigree diagram if a trait is dominant or resessive?
If a trait is dominant, it will appear in every generation where at least one parent has the trait. If a trait is recessive, it can skip generations and may appear in offspring of parents without the trait. Dominant traits are usually expressed in every generation, while recessive traits can "hide" and reappear later.
Is albinism a dominant or recessive trait?
Albinism is a recessive trait.

If the trait skips generations, it is likely recessive. Genetic testing can also help confirm the inheritance pattern of the trait.
How is a recessive trait in a pedigree?
In a pedigree, a recessive trait is typically represented by filled-in shapes (squares for males and circles for females) to indicate individuals who express the trait. A recessive trait appears in an individual only if they inherit two copies of the recessive allele, one from each parent. Consequently, unaffected parents can have affected offspring if both are carriers of the recessive allele. The pattern often shows skipped generations, as the trait can be passed through carriers without manifesting.
What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
How are phenotypes used pedigree analysis?
The pedigree will typically show one kind of trait and the affected members of a family. Take a look at if the trait is dominant or recessive first. Once you have that figured out,start to predict the genotypes of the individuals in the pedigree.

In a pedigree an open circle represents what?
Pedigree charts are a graphic representation of a family's inheritance. An open circle indicates a female homozygous recessive for a trait.
A trait that is hidden?
The trait that is hidden is recessive trait.
Is the trait being studied in the pedigree recessive or dominant?
This cannot be determined solely from a pedigree without additional information. The inheritance pattern of a trait can be deduced from the way it is passed down within a family and how it appears in the pedigree. Dominant traits will typically appear in every generation, while recessive traits may skip generations.
In human brown eyes (B) is a dominant trait and blue (b) , recessive trait?
Not my answer
How do you figure out if a trait is dominant or recessive without making an experiment?
You can determine if a trait is dominant or recessive by observing the inheritance pattern in a family. If individuals with the trait only have one copy of the allele and can pass it on to their offspring, the trait is likely dominant. If individuals need to have two copies of the allele to express the trait, it is likely recessive.
When using a pedigree chart you can distinguish between recessive and dominant traits because?
The two most straight forward ways are: - If both parents have the trait, and one of their children does not, it must be recessive. - If neither parent has the trait, and one of their children does, it must be dominant.
How is a pedigree helpful to geneticist?
Helps to track how a specific trait gets passed along. Can also help determine which traits are recessive and which aren't
