Question

The karyotype designation for an infant with a deletion in the short arm of chromosome 5 (cri du chat syndrome) is ____________

Answer 1

5p-

Step-by-step explanation:

• A karyotype of a person is used to describe the count of the chromosomes present in any organism and also, detect if any abnormality is present or not.
• For the karyotype designation the short arm of the chromosome is designated as p and the long arm is designated as q.
• Further, for the designation the pattern followed is as follows:
• Total number of chromosomes, sex chromosomes, chromosome with abnormality if any along with p/q.
• In Cri-du chat syndrome there is deletion of the short arm of the chromosome 5 and hence, the karyotype designation is - --> 46,5p- since the sex of the infant has not been mentioned in the given question.
