Abstract

On the basis of their earlier experiments the authors assumed that the ability to recognize the smell of two ketone compounds, acetone and methylethylketone (MEK), might be determined genetically. In the present work of smelling test was performed in adult Hungarian twins, 61 like sexed DZ pairs and 87 MZ pairs. No connection was found between twin zygosity and intra-pair concordance for MEK, while in the case of acetone smelling some connection may exist. A highly significant correlation was found between the smelling ability to acetone and MEK. Females seemed to be better smellers than males. Comparing the taste perception for PTC to the smell perception for acetone the supposition of a possible genetic linkage between the two traits, put forward by other authors, could not definitely be confirmed.

酮类化合物嗅觉能力:匈牙利双胞胎的研究。
在他们早期实验的基础上,作者假设识别两种酮化合物(丙酮和甲基乙基酮(MEK))气味的能力可能是由基因决定的。在本研究中,对匈牙利成年双胞胎进行了嗅觉测试,其中61对像性别的DZ对和87对MZ对。MEK的双胞胎合子性与对内一致性之间没有联系,而在丙酮嗅觉的情况下可能存在某种联系。对丙酮的嗅觉能力与MEK之间存在极显著的相关性。女性的嗅觉似乎比男性好。将PTC的味觉与丙酮的嗅觉进行比较,其他作者提出的两种性状之间可能存在遗传联系的假设无法得到肯定的证实。
