尽管不是学生物、医学之类的，但是看见这样的一幅image还是挺舒服的，毕竟它们存在于我们体内，呵呵，针对此图，单指male哦……
zhk521 发表:Chromosome Pairs in Human Cells
Online at http://cancerquest.emory.edu/index.cfm?page=648
The image below shows the chromosomes from a human cell. The depiction of all of the chromosomes in this manner is known as a karyotype. Karyotypes are often performed on fetal tissues during pregnancy to detect chromosomal abnormalities in the unborn child. These chromosomes have been colored by the binding of fluorescent dyes. Notice that there are two copies of each chromosome. The wide range in sizes of the chromosomes is also apparent. The chromosomes are numbered in the inverse order of their size. Chromosome 1 is the largest chromosome and the smallest chromosomes are those numbered 21 and 22. The karyotype shown below is from a male and contains one X and one (much smaller) Y chromosome. The DNA in even the smallest of the chromosomes contains millions of basepairs.
