Homozygote excess was observed in some wild populations and an inbreeding structure is suggested. The inbreeding coefficient (F) was estimated from the observed and expected heterozygosities and the estimates indicate the existence of two groups, one of which is a population having a higher inbreeding coefficient (0.205-0.349) and the other a lower inbreeding coefficient (<0.066). It was further observed that populations having a higer inbreeding coefficient tended to show a wider range in the relative proportion (by weight) of soft body parts to the whole body. These results are interpreted as being a reflection of the effect of both harmful and advantageous genes homozygote an inbreeding population.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"天然エゾアワビ集団における15酵素のアイソザイムを調べた.その結果197イソザイム遺伝子座が推定できた,多型遺伝子座の割合は0.421,平均へテロ接合体率(He)は0.118であった.各集団は遺伝的距離0.01で大きく2つのグループに別れたが,地理的分布との関連は認られなかった.採集地によってホモ型過剰がみられた.平均へテロ接合体率の観察値と期待値から近交係数を推定したところ11地域集団は近交係数が,
