What type of chromosomal error is most commonly associated with Turner Syndrome?
Understand the Problem
The question is asking about the specific type of chromosomal error that is most frequently linked to Turner Syndrome, which is a condition caused by the absence of one of the X chromosomes in females.
Answer
Maternal meiotic errors.
The most commonly associated chromosomal error with Turner Syndrome is monosomy X, which is a type of maternal meiotic error.
Answer for screen readers
The most commonly associated chromosomal error with Turner Syndrome is monosomy X, which is a type of maternal meiotic error.
More Information
Turner Syndrome typically results from the complete absence or partial loss of one of the X chromosomes, which leads to monosomy X. This condition is most often a result of errors in the maternal meiosis process during egg formation.
Tips
Common mistakes include misidentifying Turner Syndrome as caused primarily by errors in other processes, such as gamete fusion or DNA replication, rather than understanding its direct link to meiotic errors.
