The band Numbers increased with the increase in chromosomelength.
随着染色体长度的增加，带纹数目也增加。

The position effects of mark gene and other factors have a little influences on the expect value, but the chromosomelength have much influences on it.
标记基因的位置效应和干扰因素对这一期望值的影响是很小的，而染色体的长度对期望方差值影响很大。

In cells division chromosomelength is shorten for the ending DNA couldn't be replicated completely, and the loss of telomere DNA will lead to senescence and death.
