How many genotypes are possible in a pedigree of sex linked traits?
Wiki User
∙ 10y ago
xx = normal female
x- x = carrier female
x- x- = female which has the sex-linked trait
xy = normal male
x- y = male which has the sex-linked trait

What chart is is used to trace the history of traits in a family?
pedigree chart
What might the phenotypes be of two organisms that were found to have different genotypes but the same phenotype?
Phenotypes refer to the visible traits (or characteristics). Genotypes are the underlying causes for those traits. There may be different genotypes that cause the same phenotype. If the observable traits from one individual are the same from another individual, one can say they have the same phenotypes.
What does a pedigree show that a karyotype does not?
A karyotype shows the number of chromosomes in a species A pedigree shows traits passed through generations.
A trait controlled by a gene on the sex chromosome is know as a?
Sex-linked traits
What is the difference between a monohybrid and dihybird cross?
monohybrid cross deals with one genotypic trait whereas the dihybrid cross deals with two traits being crossed to see the possible genotypes.
Describe how phenotypes can be used to predict genotypes in a pedigree?
By observing the phenotypes of individuals in a pedigree (such as their physical characteristics or traits), one can infer the genotypes that may be responsible for those traits. By looking at patterns of inheritance within the pedigree, such as autosomal dominant, autosomal recessive, or X-linked inheritance, one can make educated guesses about the genotypes of individuals based on their observed phenotypes. However, the presence of genetic variability, incomplete penetrance, or phenocopies can complicate the prediction of genotypes solely based on phenotypic information.
How is it possible for two individuals to have the same phenotype but different genotypes for a traits?
it is possible beccause you dont always need both
What are the probable mode of inheritance from a pedigree diagram showing phenotypes?
The modes of inheritance are y-linked, x-linked, and mitochondrial. Inherited traits can then be recessive, dominant, or autosomal depending on how they are inherited.
What are the differences between a punnett square and a pedigree?
A Punnett square is a tool used to predict the possible genetic outcomes of offspring based on the genotypes of the parents, while a pedigree is a diagram that shows the inheritance of a specific trait or genetic condition within a family over multiple generations. Punnett squares focus on genetic probabilities, while pedigrees focus on tracking genetic traits through family history.
What chart is is used to trace the history of traits in a family?
pedigree chart
How does a geneticist use a pedigree?
A geneticist would use a pedigree to trace the inheritance of traits in humans.
A pedigree chart shows relationships within a family?
A pedigree shows the possible outcomes of traits in offspring. It shows if the offspring will have the trait, or if they will be a carrier. Pedigrees also show the previous generations how the future generations inherited the trait. The past generations can be labeled as F1 and the future are F2, which is our current generation.
What genotypes covers up other traits?
dominant trait
What might the phenotypes be of two organisms that were found to have different genotypes but the same phenotype?
Phenotypes refer to the visible traits (or characteristics). Genotypes are the underlying causes for those traits. There may be different genotypes that cause the same phenotype. If the observable traits from one individual are the same from another individual, one can say they have the same phenotypes.
How are sex-linked traits inherited?
Sex-linked traits are inherited from the organism's parents.
What does a pedigree show that a karyotype does not?
A karyotype shows the number of chromosomes in a species A pedigree shows traits passed through generations.
What is used to track traits within a family line?
A pedigree is used.
