Question

a karyotype (in figure 1) shows which of the following? figure 1: human karyotype image of karyotype
○ autosomes (1-22)
○ sex chromosomes (23rd)
○ homologous chromosomes
○ all of the above

Explanation:

1. Autosomes are the non - sex chromosomes (1 - 22 in humans), and the figure shows chromosomes 1 - 22 which are autosomes.
2. Sex chromosomes (the 23rd pair, X and Y) are also part of the human karyotype, and the figure includes the sex chromosome pair.
3. Homologous chromosomes are chromosome pairs (one from each parent) that are similar in length, gene position, etc. In a karyotype, each pair of chromosomes (including autosomes and sex chromosomes) are homologous. So all the options (autosomes, sex chromosomes, homologous chromosomes) are represented in the human karyotype figure.

Answer:

D. all of the above
