Why are sex linked recessive conditions more likely in males then females?
Because females have TWO X chromosomes. Males only have one. that means if the recessive gene is on the X chromosome it becomes evident phenotypically.
Described how sex - linked are expressed differently in males and in females?
In humans, females (XX) have two X chromossomes whereas males only have one. While most of one of the X chromossomes is deactivated in females it's still less likely for females to get an X-linked genetic disorder unless in double dose or a dominante gene. For males (XY), on the other hand, since they only have one X chromossome that isn't deactivated, one dose is usually enough to cause them to have the disorder, whether the gene is recessive or dominant. That's why males are way more likely to get such disorders than females. Hemofilia, daltonism and baldness would be three examples. Traits linked to the Y chromossome will practically always manifest in males, and never in females. Hairy ears would be one example.
Why are sex-linked traits more conman in males?
Because males have XY configuration of sex chromosomes and females XX. So in xy situation even the recessive gene can express. That is why sex-linked characters in males are more common than females.
Assume that a particular genetic condition in a mammalian species causes an inability to digest starch This disorder occurs with equal frequency in males and females in most cases neither parent is af?
This genetic condition is likely an autosomal recessive trait since it occurs with equal frequency in males and females. If neither parent is affected, it suggests that both parents are carriers of the condition. In order for a child to be affected, they would need to inherit two copies of the recessive allele, one from each carrier parent.
Are males most likely to have an x-linked disorders?
Males are much more likely to be affected by an x-linked disorder because they only have one copy of the x-allele, so if they carry an abnormal version, it will be expressed. On the other hand, since women have two copies of the x-allele, they would need two copies of the abnormal gene to show the disease.
What is the main reason that sex-linked disorder are most often observed in males?
Males are most likely to have the disorder.
What is a sex-linked linked genetic disorder?
color blindness is one
What is the main reason sex linked disorders are the most often observed in males?
Males are most likely to have the disorder.
Why are males more likely than females to have a sex linked traits that are recessive?
Because they olny have one X chromosome.
Why are males more likely than female to have a sex linked trait that is recessive?
Because they olny have one X chromosome.
Why are sex linked recessive conditions more likely in males then females?
Because females have TWO X chromosomes. Males only have one. that means if the recessive gene is on the X chromosome it becomes evident phenotypically.
Why are sex linked disorders seen in mostly males?
Males are most likely to have the disorder.
Since red - green color weakness is recessive and sex linked the incidence of this color weakness is likely to be greatest among what?
Males
Why are males most likely to express a sex linked recessive trait?
Males have only one X chromosome, so a recessive X-linked trait will be displayed in the phenotype [visible on the outside]. Females have two X chromosomes, so both of the chromosomes must have the trait for it to be displayed on the phenotype.
Does Wiskott-Aldrich syndrome affect women?
Yes, although it is rare in women. 90% of cases are found in males. Its an X-linked recessive disorder. Which means we can also be carriers of WAS.
Why are x linked alleles expressed in males even if they are recessive?
X-linked are not recessive nor dominant. X-linked just do not show. On the sex-linked chromosomes the Y chromosome of the X-Y pair dominates the trait whether its recessive or dominant!Actually, all x-linked alleles are expressed because males only have one x-chromosome, so whatever is there, dominant or recessive, is expressed.
Is colorblindness a dominant or recessive trait?
Color blindness is an inherited trait that can be passed on through reproduction but it has some peculiarities. It is recessive and not very prevalent in the gene pool. Because of this, color blindness does not appear very often in the population. In addition, it is a sex-linked gene on the X chromosome. Thus males only have one gene to express color vision. If it happens to be the recessive allele, then males are color blind. Females, on the other hand, must have both alleles recessive in order to be color blind.source: ciese.org/curriculum/genproj/activity35.html
