They are not "more common",
but since they are not paired in the male there's no such thing as a recessive.

Is Colorblindness sex-linked or autosomal?
It's sex-linked recessive because the defect is on the X-chromosome. It's more common in male because of this fact. In order for a female to have it, she'd have to have defective genes on both of her X-chromosomes.yes, colour blindness is passed through the mother's gene
Is blonde hair recessive or dominant?
Recessive gene of X chromosome. more common in men as they have only one x chromosome but in female there are 2 X chromosome. If one of X chromosome in female has this recessive gene, they become a carrier. If both the X chromosome in female has this gene, they show baldness
Is Klinefelter Syndrome sex-linked or autosomal?
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.
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.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
Why are sex chromosome abnormalities more common?
Sex chromosome abnormalities are far more common than abnormalities of the other 44 chromosomes (the autosomes) because they rarely produce deadly diseases.
What would the karyotype look like for a male where would the chromosome be?
The question is not complete. You need more context than this. What chromosome is it? 21? 23? 5? it autosomal? cmon man i cant answer this

Is edwards syndrome more common in boys or girls?
Edwards syndrome (trisomy 18) occurs more frequently in girls than boys. It is a genetic disorder caused by the presence of an extra copy of chromosome 18, leading to developmental abnormalities and various physical and mental impairments.
What chromosome is Proteus syndrome located?
Proteus Syndrome more common in mails or females?
What does a drop in white blood cells mean?
If it is mild and there are no other abnormalities it usually means nothing. It is more common for people of African descent. If it is severe or there are other abnormalities in the blood counts then it may be something to have further evaluated.
Is polydactyly common in men or women?
Polydactyly is more common in men, because it is a genetic disorder. Because females have 2 X chromosomes, a recessive trait passed down on one will be covered by the dominant trait on their other X chromosome for no polydactyly. Males though, have an X and Y chromosome which means that that the Y chromosome, carrying no trait for polydactyly, will not affect an X chromosome with the allele for polydactyly. Hence, polydactyly is found in men more than women.
Why does the X chromosome affect an organisms phenotype more than the Y chromosome?
The X chromosome contains considerably more genetic material than the Y chromosome.
Why are traits controlled by recessive alleles on the X chromosome are more common in males than in females?
Males only have one X chromosome, so even if the gene on that chromosome is recessive there is no other gene that could dominate it. Females have two X chromosomes, so if the gene on that chromosome is recessive there is still a chance that the gene on the other chromosome could be dominate and override it.
Is blonde hair recessive or dominant?
Recessive gene of X chromosome. more common in men as they have only one x chromosome but in female there are 2 X chromosome. If one of X chromosome in female has this recessive gene, they become a carrier. If both the X chromosome in female has this gene, they show baldness
Is down syndrome autosomal or sex-linked?
No. It is due to a non-disjunction problem when the sperm and egg meet to form a zygote.
Is Klinefelter Syndrome sex-linked or autosomal?
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.
