What can be determined from looking at a pedigree?
patterns of familial inheritance. patterns of sex-linked inheritance.
Could the trait that is traced by this pedigree be sex-linked?
To determine if a trait traced by a pedigree is sex-linked, one would look for patterns in the inheritance of the trait, particularly its distribution among males and females. If the trait primarily affects one sex more than the other, or if it appears to skip generations, it may indicate a sex-linked inheritance pattern, especially if the trait is more common in males. Additionally, if affected males pass the trait to all their daughters but none of their sons, this supports the idea of a sex-linked trait. However, a full analysis of the pedigree is necessary for a definitive conclusion.
How might a scientist determine whether a trait is a sex-linked by observing the offspring of several genetic crosses?
no
How can you tell if a genetic disorder in a pedigree chart is sex linked?
In humans (and other animals with the XX/XY sex chromosome configuration) a sex linked trait will show up in sons 50% of the time and 0% of the time in daughters of a female carrier.The only way that a female can have the necessary phenotype/genotype to display the trait is for thefather to be affected and the mother to be a carrier or affected herself.
What do you call the genes that are located on the sex chromosomes?
genes located on sex chromosomes are called sex-linked genes. In humans, there are two types of sex chromosomes: X and Y chromosomes.Genes located on the X chromosome are called X-linked and genes located on the Y chromosome are called Y-linked chromosomes.
How many genotypes are possible in a pedigree of sex linked traits?
In a pedigree of sex-linked traits, there are three possible genotypes for males: XY (unaffected), XeY (affected), and XeX (carrier). For females, there are two possible genotypes: XX (unaffected) and XeX (carrier). This makes a total of 5 possible genotypes in a sex-linked trait pedigree.

patterns of familial inheritance. patterns of sex-linked inheritance.
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.
How do pedigrees for autosomal genes differ from pedigree for sex-linked genes?
sex-linked genes are differ from autosomal from pedigrees because they both have different affects from pedigrees
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.

A genetic pedigree showing that only males are affected by a certain disorder is evidence of what type of inheritance?
Sex-linked.
How might a scientist determine whether a trait is a sex-linked by observing the offspring of several genetic crosses?
no
How can you distinguish between a sex linked disorder and sex limited from the pedigree?
A sex linked disorder will show up in males and females, but it will show up twice as much in the males. A sex limited disorder will show up in only one gender. If it is onlyfemales, then you know that it's sex limited. If it is onlymales, then it is sex limited.
Is hemophelia sex influenced or sex-linked?
The gene for hemophilia is sex-linked.

Is hemophilia a sex-linked inheritance disease?
Yes, hemophilia is sex-linked.
