The pearl oyster Pinctada martensii is an important species for sea production in China. To explore the influence of combination mass selection and hybridization on growth performance P. , we established four selected groups control (each with two within-family crosses reciprocal hybrid crosses) using 1-year-old offspring families (Family A Family B) from Beihai, Guangxi Province, Generally, gr...

Family studies of exceptional longevity can potentially identify genetic and other factors contributing to long life and healthy aging. Although such studies seek families that are exceptionally long lived, they also need living members who can provide DNA and phenotype information. On the basis of these considerations, the authors developed a metric to rank families for selection into a family...

Eggshell quality is the main trait to assess egg quality. Marker assisted selection can be used to improve this trait. During eggshell formation, a mass of inorganic minerals is deposited. The Sodium Channel (SCNN1) gene family plays an essential role in cation transportation and SCNN1g is a member of this gene family. The objective of this study was to estimate the frequency of SCNN1g gene var...

The selection of a best-subset regression model from a candidate family is a common problem that arises in many analyses. In best-subset model selection, we consider all possible subsets of regressor variables; thus, numerous candidate models may need to be fit and compared. One of the main challenges of best-subset selection arises from the size of the candidate model family: specifically, the...

We investigated the possibility of positive selection acting on members of the putative seven-pass chemoreceptor superfamily in Caenorhabditis elegans, which comprises approximately 1,300 genes encoding seven-pass G protein-coupled receptors (GPCRs). Using a maximum-likelihood approach, we conducted statistical tests for evidence of codon sites where the ratio of nonsynonymous substitutions per...

background: health measurement is one of the major challenges in today’s researches. various indicators including well‑being are used to evaluate health. many factors including culture, structures, and values can be effective on family health, quality of life, and well‑being of family members that these elements themselves are effective on the whole society’s health. one of other effective fact...

Uniformly most powerful confidence distributions are obtained for parameters in selected models of the exponential family. A conditioning on selection event as well sufficient statistics nuisance guarantees valid post-selection inference. Optimal intervals directly from distribution without requiring an inversion pivotal quantities. Simulations showcase that method works also when all misspecif...
