Males have XY - therefore they only need one copy of the defective X in order to have the disorder.
Females have XX - meaning they would need two copies of the defective allele in order to have the disorder. This means their father must have the disorder, and their mother must either have the disorder or be a carrier.

Which gender has a higher frequency of sex linked traits?
Males typically have a higher frequency of sex-linked traits because they have only one X chromosome, making recessive sex-linked traits more likely to be expressed. Females have two X chromosomes and can be carriers of recessive sex-linked traits without showing the phenotype.
In the case of sex linked traits only females can be carriers true or false?
False. In the case of sex-linked traits, specifically those linked to the X chromosome, both males and females can be affected, but only females can be carriers for X-linked recessive traits. Males have only one X chromosome, so if they inherit an X-linked recessive trait, they will express it rather than be a carrier. Females, having two X chromosomes, can carry one normal and one affected allele, making them carriers without expressing the trait.
Why are males more likely than females to have a sex linked traits that are recessive?
Because they olny have one X chromosome.
Why do you sex linked traits follow different patterns of inheritance then other traits?
Males and females have different sex chromosomes.
When do females express a sex linked recessive trait?
Females express a sex-linked recessive trait when they have two copies of the recessive allele, one on each of their X chromosomes. Since females have two X chromosomes (XX), they must inherit the recessive allele from both parents to exhibit the trait. If they have only one copy of the recessive allele and the other X carries a dominant allele, the dominant trait will be expressed instead. Examples of sex-linked recessive traits include hemophilia and color blindness.
What are the sex-linked traits in humans and how do they differ between males and females?
Sex-linked traits in humans are genetic characteristics that are carried on the sex chromosomes, X and Y. In males, who have one X and one Y chromosome, sex-linked traits are typically passed down from the mother on the X chromosome. In females, who have two X chromosomes, sex-linked traits can be passed down from both parents. This means that males are more likely to exhibit sex-linked traits if they inherit a recessive gene on their X chromosome, while females need to inherit two recessive genes, one from each parent, to show the trait.
Traits determined by recessive genes located on the x chromosomes are said to be?
Some traits are determined by recessive genes on the X chromosomes. Many times these are genetic disorders and are called recessive genes.
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.
Describe sex-linked traits and state the predictable modes of inheritance for traits located on the X chromosome.?
Sex-linked traits are traits that are held in the x-chromosome, Males are more than likely to than females to have to have x-linked traits due to them only having one x chromosome which makes them more vulnerable. While females need to inherit two recessive genes/alleles to have and express the condition.
Why are sex link traits more common in male than females?
Sex-linked traits are more common in males than in females. This because recessive allele in the X chromosome and produces the trait in males.
Why would recessive traits be more common on boys than girls?
Only sex-linked recessive traits on the X sex chromosome are more common in males. This is because males receive only one X chromosome, so they cannot be heterozygous for a trait on the X chromosome. Females inherit two sex chromosomes, so they can be heterozygous, receiving both a dominant and a recessive allele on the X chromosomes.
What is an X linked traits?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
