Hirado: temporal trends in inbreeding and fertility.

Hirado: temporal trends in inbreeding and fertility.

Until recently, it has been commonplace both to deplore the lack of realism in most, if not all, genetic models used in the study of human populations and to acknowledge that few data existed from which improvements might stem. Interest and energy have, however, begun to focus upon the collection of data which hopefully will serve as bases for the formulation of more insightful and presumably m...

Fertility Trends and Implications

Inbreeding effects on fertility and sterility in southern India.

The effects of consanguineous marriages on couples' fertility and sterility were explored through an interview survey of 20 626 women, chosen randomly from the rural and urban areas of the North Arcot District of Tamil Nadu State. Qualified women investigators obtained relevant information about reproductive performances of all married women resident in well defined rural and urban samples chos...

Late Fertility Trends in Europe

European continent has been for-runner in the demographic transition process. Age-specific fertility patterns had changed tremendously during this process in Europe. However, it is still mainly concentrated in the female age group 20 – 34 years. Women and couples tend to limit fertility in marginal age groups of female's reproductive period. In this paper the author addresses late agespecific f...

Effects of inbreeding and other genetic components on equine fertility.

The Finnish mating records of Standardbred trotters (SB; n = 33 679) and Finnhorses (FH; n = 32 731) were analysed to study the effect of the level of inbreeding on foaling rates and to estimate the heritability of foaling rate. A linear mixed model was assumed, with the outcome of the foaling (foal or no foal) as the trait of the study. A restricted maximum likelihood-based method was used to ...
