Maternal Genetic Disease

Can we define maternal age as a genetic disease?

>Maternal age is strongly associated with a decrease in the probability of achieving pregnancy and the birth of a healthy child. Among current theories of the mechanism of this decrease is the hypothesis that a progressive degeneration of the respiratory capacity of mitochondria in eggs of women of advanced age leads to an energy deficit and consequent secondary effects on the oocyte and develo...

Genetic Mutations that Cause Coronary Artery Disease

Genetic influences on maternal care.

The basis of social evolution in mammals is the mother-offspring relationship. It is also the primary and most important instance of indirect genetic effects, where genetic variation in one individual affects phenotypic variation among others. This relationship is so important in mammals that often the major factor determining the life or death of newborns is the environment provided by their m...

Genetic Aspects of Maternal Ability in Sows

Grandinson, K. 2003. Genetic aspects of maternal ability in sows. Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6440-4 The purpose of this thesis was to gain knowledge about the genetic background of different aspects of maternal ability in sows. Today’s selection for increased litter size at birth will put higher demands on the sow’s ability to take care of her litter, and may cause probl...

Maternal genetic effect of resistance to rice yellow mottle virus disease in rice

Reciprocal selection is a breeding procedure for population improvement and hybrid development. Both female and male parents contribute genes to their offspring, but the influence of female parent often extends beyond simple genetic transmission. Nine parents were crossed in a full diallel and evaluated for maternal genetic effects for resistance to rice yellow mottle virus disease. This study ...
