Many sex-linked disorders come from the X chromosome. (Either gender can obtain the disorder, however, it is harder for a female to get it than a male). Very few sex-linked disorders occur on the Y chromosome. (Only males can obtain these disorders).
Sexlinked and recessive.
Apert syndrome is a autosomal dominant genetic disorder, meaning that only one copy of the mutated gene from either parent is necessary to inherit the condition. It is not sex-linked.
Males are more likely to get recessive sex-linked disorders because they have only one X chromosome, meaning they will display the disorder if that X chromosome carries the recessive gene. Females, on the other hand, have two X chromosomes which can often mask the presence of the disorder if one X chromosome carries a normal allele.
it means that you inherit this form of disorder either from your mother or father's sex chromosomes. For example- color blindness or Haemophillia.
Hemophilia, a blood clotting disorder, is an example of a sex-linked recessive defect. It occurs more commonly in males because the gene for hemophilia is located on the X chromosome. Females are usually carriers of the gene but are less likely to exhibit symptoms.
Genes that are location on the sex chromosomes.

More boys than girls have it before puberty starts, but it's about equal after puberty.
Males are more likely to get recessive sex-linked disorders because they have only one X chromosome, meaning they will display the disorder if that X chromosome carries the recessive gene. Females, on the other hand, have two X chromosomes which can often mask the presence of the disorder if one X chromosome carries a normal allele.
Certain genetic defects occur on the sex chromosomes, either X (female) or Y (male).
Males are most likely to have the disorder.
more common in boys than girls before puberty ; the disorder typically begins by age eight. After puberty the male:female ratio is about 1:1.
No. The children of same sex couples are not more likely to be gay.
Males are most likely to have the disorder.
it means that you inherit this form of disorder either from your mother or father's sex chromosomes. For example- color blindness or Haemophillia.
Simply a trait or disorder that resides on one of the sex chromosomes. XX for female and XY for male. Since the X chromosome carries significantly more genes than the Y we see more traits and disorders appearing on this chromosome and also it is statistically more likely for males to express disorders on this chromosome, especially recessive, as they have only one X chromosome.
