Is Turner Syndrome dominant or recessive?
Genes are often dominant or recessive. Since one X chromosome is missing in Turner Syndrome, it doesn't matter, since there is no other X chromosome with a pairing gene.
Trick question: it's sex-linked. So, recessive in females and dominant in men. Rarely will you see a sex-linked gene that is sex-linked dominant, but they do exist.
I apologize. PsyDAG is correct. Turner syndrome is a monosomy trait. So, it's not considered recessive, dominant, or sex-linked.
To determine whether Turner Syndrome is dominant or recessive, we need to understand the genetic basis of this condition. Turner Syndrome is not caused by any dominant or recessive allele on an autosome (a non-sex chromosome). Instead, it is a condition that occurs due to a chromosomal abnormality involving the sex chromosomes.
Typically, individuals have two sex chromosomes, either XX (female) or XY (male). However, in Turner Syndrome, females are born with only one fully functional X chromosome or are missing a part of one X chromosome. This condition is represented as 45,X or 45,X0.
As Turner syndrome is not caused by a single gene with dominant or recessive inheritance, it cannot be classified as dominant or recessive. It is a chromosomal disorder caused by a random error during development, and its traits and symptoms are caused by the absence or partial absence of an X chromosome.
It's important to note that the inheritance of Turner Syndrome is generally not passed down from parent to child. Most cases occur sporadically, meaning they happen by chance and are not inherited.
