How is coffin-lowry syndrome inherited? Do both parents need to have the disorder in order for their child to have it?

Coffin-Lowry syndrome is caused by changes (mutations) in the RPS6KA3 gene and is inherited in an X-linked dominant pattern. Males are usually more severely affected than females.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
