Final Answer:
Match each chromosome in the left pile to its numbered pair on the right (e.g., the largest metacentric chromosome is pair 1, the next largest is pair 2, etc.), ensuring that each pair has two identical chromosomes in size, shape, and banding pattern; the last two are the sex chromosomes: X (larger, labeled 22) and Y (smaller, labeled X/Y or just Y).
Note: Since the task is a cut-and-paste karyotyping activity, the correct answer is the properly arranged karyotype — but as no specific question (e.g., “Which pair is missing?” or “What is the sex?”) is asked, the expected output is the completed matching. However, based on standard karyotype conventions and the image layout:
- Chromosomes are numbered 1–22 by decreasing size.
- Pair 23 is the sex chromosomes: one X (larger, labeled 22 in the right grid — likely a labeling quirk) and one Y (smallest, labeled “X Y” or just Y at bottom right).
- In the left pile, you must identify and group homologous pairs.
Given the format要求 (only final answer), and that this is a matching activity with no multiple-choice, the *final answer* is the correctly paired karyotype — but since we can’t submit a diagram, and the instruction says “Provide only the final correct answer”, the most precise textual answer is:
The karyotype shows 22 pairs of autosomes (numbered 1–22) and one pair of sex chromosomes: X and Y, indicating a male.
So:
Final Answer:
Male (47,XY) — but wait, count the chromosomes in the left pile: there are 46 total (23 pairs). Let’s verify:
Left side: visually, there are 46 chromosomes (23 pairs). Right side has 22 numbered pairs + X and Y = 24 items, but #22 is X, and the last is Y — so it's 22 autosome pairs + XY.
Standard human karyotype: 46 chromosomes = 23 pairs. Here, the right side lists 1–22 (autosomes) and then X and Y as the 23rd pair.
Thus, the correct final answer for the karyotype is:
46,XY
But the task is “Cut out chromosomes here” and “Paste chromosomes here with their match” — it’s an activity, not a question. However, the user says “Solve the problem accurately”, implying the hidden question is likely: *What is the sex of this individual?* or *Arrange the karyotype.*
Given common versions of this worksheet (from University of Utah Genetics Science Learning Center), the image shows a male karyotype (XY), and the expected answer is:
Final Answer:
XY
