What is the diagnostic tool that reveals missing or extra chromosomes and some structural changes in an individual's chromosomes?
Karyotyping
The failure of replicated chromosomes to separate is called?
The failure of replicated chromosomes to separate is called nondisjunction. This will cause extra or missing chromosomes in the daughter cells.
What mutation causes either the inclusion of an extra chromosomes in offspring or the deletion of an entire chromosomes?
non-disjunction
What clues to the presence of certain genetic disorders can be seen in a karyotypes?
-Extra, missing or damaged chromosomes could show the presence of genetic disorders.
Identify several things that can be seen with a karyotype?

What causes a baby to come out deformed?
Mutations in their chromosomal DNA. Each parent gives chromosomes to the baby, and when they meet sometimes there are doubles of chromosomes, missing chromosomes, or mutated chromosomes which cause abnormalities in the DNA and overall the child.
What happens if a human has too many or too few chromosomes?
It depends on which chromosomes were present as to what the abnormality would be, if any. If they were missing one or had one extra there would be developmental abnormalities.
What chromosomal abnormality causes Turner syndrome?
If one of sex chromosomes is missing. Normal-XX Turner- XO
What genes or chromosomes is the muitation that causes turners syndrome?
Turner syndrome is the result of one of the two X chromosomes being missing or damaged in some or all cells. These chromosomes are the sex chromosomes, which determine whether a person will be male or female. As people with Turners only have an X chromosome and no Y chromosome they are born female.
