2. In order from left to right, to which groups do the chromosomes shown belong?

A. group A, group C, group D, group G B. group G, group A, group D, group C C. group G, group A, group C, group D D. group A, group G, group D, group C

Correct Answer: B. group G, group A, group D, group C Explanation: Before the technology existed to identify individual chromosomes, they were classied into groups based primarily on their length. There are seven groups, labeled A through G, with group A containing the longest chromosomes and group G the shortest. If we rank the four chromosomes, from left to right, according to length they are shortest, longest, second shortest, and second longest. The only answer that could correspond to this order is answer B.

Correct Answer: A. a female with Turner's syndrome Explanation: The karyotype shown includes only one sex chromosome, an X. This condition is called Turner's syndrome and results in a female.
