objective: maternal type and amounts of dietary fatty acids affect on reproductive process in the mice. the present study investigated the effects of maternal supplementation with different amounts of omega-6 or omega-9 during pregnancy on the number of offspring, sex-ratio and duration of gestation. materials and methods: eight-week-old female c57bl/6 mice were randomly assigned into four diet...

In seasonal environments, many species concentrate their reproduction in the time of year most likely to maximize offspring survival. Asian elephants (Elephas maximus) inhabit regions with seasonal climate, but females can still experience 16-week reproductive cycles throughout the year. Whether female elephants nevertheless concentrate births on periods with maximum offspring survival prospect...

this study was conducted to evaluate the effects of maternal diabetes on fetal spinal structure, especiallyin brachial enlargement. sixteen adult female rats were divided into two groups. diabetes was induced in one group by alloxan agent. both groups became pregnant by natural matting. on days 7, 14, 21 and 28 after birth, the brachial enlargement of the spinal cord was collected from offsprin...

This paper shows a new algorithm to calculate the mean and temperature of multi-branch combinatorial games. The algorithm gradually, one node at a time, expands the offspring of a game. After each step of expansion, the lower and upper bounds of the mean and temperature of the game is re-calculated. As the expanding process continues, the range between the lower and upper bounds is narrowed. Th...

Consider a Galton-Watson process with immigration. The limiting distributions of the non-sequential estimators of the offspring mean have been proved to be drastically different for the critical case and subcritical and supercritical cases. A sequential estimator, proposed by Sriram, Basawa and Huggins (1991), was shown to be asymptotically normal for both the subcritical and critical cases. Ba...

The objective of this study was to evaluate the imputation accuracy of parent-offspring trios under different scenarios. By using simulated datasets, the performance Bayesian LASSO in genomic prediction was also examined. The genome consisted of 5 chromosomes and each chromosome was set as 1 Morgan length. The number of SNPs per chromosome was 10000. One hundred QTLs were randomly distributed a...

Revolution and Family in Rural China: Influence of Family Background on Current Family Wealth This paper examines the influence of family human capital on offspring’s economic status in post reform rural China by concentrating on the father-son relationship. We focus on two indicators of family background: family class origin (jiating chengfen) and occupational experience. The results of a fami...

This article studies the effect of parental background on the educational attainment of the offspring. In particular, it compares the effects of parental occupation and education and investigates whether the relative importance of these resources have shifted over time. In addition, this article studies, which parent has the strongest effect on the offspring’s education. Using data for the Neth...
