Females
have two X chromosomes and males only have one–and this simple fact, along with the occurrence of what geneticists call mosaicism, may not only explain why women are less susceptible than men to certain genetic diseases, but also may account for the female prevalence in the incidence of other conditions and …
What genetic disorder only affects males?
Affected Populations
XYY syndrome
is a rare chromosomal disorder present at birth that affects only males. It is estimated to occur in approximately one in 1,000 live births.
Why are males more vulnerable to genetic disorders than females?
Because females have two copies of the X chromosome and males have only one X chromosome,
X-linked recessive diseases

that links the X or Y chromosome to the deviant behaviour of serial killers. Gosavi Gajbe conducted a study looking at the role of chromosomes in criminality.
What are 2 disorders that only affect males?
This is why so many male-only diseases are attributable to defective genes on the X chromosome.” Such diseases include
Duchenne muscular dystrophy, hemophilia and Hunter syndrome
, which causes dwarfing, abnormal bones and mental retardation in males but usually does not affect females who carry the same mutated gene.
What is Superman syndrome?

is a genetic condition that occurs when a male has an extra copy of the Y chromosome in each of their cells (XYY). Sometimes, this mutation is only present in some cells. Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome.
