When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation

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.
Can a human pedigree be used to detect a recessive trait?
Yes, a human pedigree can be used to detect a recessive trait by tracking the inheritance pattern of the trait within a family. Patterns such as multiple affected siblings, skip generations, and consanguinity can help identify recessive trait inheritance. Pedigree analysis can reveal carriers of the trait even if they do not show symptoms.
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.
This pedigree is for a human genetic disease called sickle cell anemia. Assuming that the allele for the disease is recessive how many of the females shown have the disease?
None. =]
What are some common challenges faced when analyzing autosomal recessive pedigree problems?
Some common challenges when analyzing autosomal recessive pedigree problems include incomplete family medical history, consanguinity within the family, small family size, and the presence of other genetic disorders that may complicate the analysis.

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
What is the pedigree of a rare recessive phonotypr determined by a recessive allele?
this question makes no sense.

How is pedigree helpful to scientists?
A pedigree is helpful to scientists because then they can figure out what trait and/or sex-linked disorder is being passed on and if it is going away.
What is use of pedigree?
Pedigree is used to determine wheather a trait is inherited.
What is a horse pedigree analyst?
A pedigree analyst studies the pedigree of a horse to help determine its potential as an athlete
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.
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.
How is a pedigree?
A pedigree is used to determine whether you are at risk of inheriting a particular genetic disorder.
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.
