结论：额外小染色体来源于Y染色体。
Conclusion the extra small chromosome is part of the chromosome Y.
一种叫微阵列(microarray)的新仪器，即一块覆盖着DNA序列的小芯片，可以同时分析染色体上的很多点。
A new device called the microarray, a small chip coated with DNA sequences, can simultaneously analyze many more spots on the chromosomes.
另外的一些人希望更多了解自己：一个团体叫DIYgenomics团结一致了分析他们的染色体组，甚至进行和参与小临床试验。
Others hope to learn more about themselves: a group called DIYgenomics has banded together to analyse their genomes, and even conduct and participate in small clinical trials.
此外，观察了前期I的簇毛麦染色体形态，统计了四分体和小孢子中小麦和簇毛麦染色质微核频率。
Otherwise, the chromosome morphology involving Haynaldia chromatin was observed at preleptotene I, and the frequencies of chromatin nucleus at tetrad stage and at microspore stage were investigated.
由此说明，基因型对秋水仙碱处理离体小孢子诱导染色体加倍的反应不同。

点突变、小和大规模的缺失、染色体异常。
Point mutations, small and large-scale deletions, chromosomal abnormalities.
之后，DrNoggle和DrEgli就能从这个小胚胎细胞得到多能干细胞-但这一细胞即拥有卵细胞又拥有表皮细胞的染色体，所以还不能用于医疗用途。
Dr Noggle and Dr Egli were then able to create pluripotent stem cells from their tiny embryo-but these had chromosomes both from the egg and the skin cell, making them useless for therapy.
