Of the 61 pairs of twins, 11 were misclassified by their mothers. Despite these mothers’ erroneous beliefs about the zygosity of their twins, they described the twins as having similarities and differences appropriate to their true degree of genetic relatedness.","PeriodicalId":78250,"journal":{"name":"Eugenics quarterly","volume":"15 1","pages":"34-40"},"PeriodicalIF":0.0,"publicationDate":"1968-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19485565.1968.9987750","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"16825442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four successive dependent variables are educational attainment, intelligence at maturity, occupational achievement, and monetary earning. Results indicate that the ideal of equal educational opportunity is realized in the white population studied to the extent that progress through the school system is influenced at least as much by how bright you are as by “who” you are. However, the fact that the latter, indexed by measures of family size and status, does make a substantial difference in educational outcome, apart from its correlation with intelligence, is an indication that the ideal is far from being completely realized at this time.","PeriodicalId":78250,"journal":{"name":"Eugenics quarterly","volume":"15 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"1968-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19485565.1968.9987747","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"16775312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct psychological effects of being able to control the sex of a child in line with preferences are considerable and almost wholly positive for both parents and children. For example the conception of children of an undesired sex is often damaging from a mental health standpoint. It is probable that ability to control sex of offspring would reduce birthrates although the magnitude and even the existence of this hypothesized relationship is highly conjectural because the prediction rests on numerous unquantified variables. A general desire for sons or daughters in a particular culture might promote a sharp imbalance in the sex ratio which would have many social and psychological consequences in the next generation. However a government determined to keep the overall sex ratio within some \"healthy\" predetermined limits could do so while permitting individual couples to have at least one child of each sex. Predictions of the reactions of religious political and other organizations to control over sex of children are impossible to make but they may be favorable in some instances.","PeriodicalId":78250,"journal":{"name":"Eugenics quarterly","volume":"14 4","pages":"274-81"},"PeriodicalIF":0.0,"publicationDate":"1967-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19485565.1967.9987737","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17150424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
