population genetics

Japanese: population genetics(英語表記)populationgenetics
population genetics

...Currently, important issues in this field include the mechanisms of gene mutations and chromosomal abnormalities induced by ionizing radiation, ultraviolet light, and even chemicals, the mechanisms of DNA damage and its repair caused by these mutagens, analysis of the genetic and environmental factors that modify sensitivity to mutagens, and the use of mutagens in breeding.
[Population genetics]
C. Darwin (1859) obtained a great deal of evidence showing that the evolution of living organisms is the result of selection, but he was unable to clarify the mechanism by which the mutations that are the subject of selection emerge. Research into natural and artificial mutations in genes provided a major clue to this problem, and genetics became deeply involved in elucidating the mechanism of evolution.

Japanese:

…現在この分野では電離放射線や紫外線,さらには化学物質による遺伝子突然変異や染色体異常の誘発機構,これら変異原mutagenによるDNAの損傷とその修復の機構,変異原に対する感受性を修飾する遺伝的・環境的要因の解析,さらには変異原の育種的利用などが重要な問題となっている。
[集団遺伝学population genetics]
 C.ダーウィン(1859)は生物の進化が淘汰によることを示す多くの証拠を得たが,淘汰の対象となる変異の出現機構については明らかにできなかった。遺伝子の自然および人為突然変異の研究はこの問題に大きな手がかりを与え,遺伝学が進化機構の解明に深くかかわることとなった。…
