Do type B women have more offspring
Though several studies have examined the relationship between parental ABO blood types and reproductive success, results have been inconsistent. In this paper, the relationship is considered using the data collected by Newton Morton and colleagues from a sample of 1,068 nuclear families of migrant workers in Brazil. Morton et al., using segregation analysis, compared parental and offspring generations and found evidence of selection acting throug…
Association of ABO phenotypes and body weight in a sample of Brazilian infants
The relationship between body weight and ABO blood types was examined in a sample of infants included in a sample of Brazilian migrant families collected by N.E. Morton 30 years ago. The results, obtained by one‐way analyses of variance using SPSS Release 4, indicate: (1) an excess of females (N = 85) over males (N = 56) due almost entirely to an excess of type A and type B females, (2) no significant differences in body weight by ABO blood type …
