We tested whether directional selection on an index-based wing character in Drosophila melanogaster affected developmental stability and patterns of directional asymmetry. We selected for both an increase (up selection) and a decrease (down selection) of the index value on the left wing and compared patterns of fluctuating and directional asymmetry in the selection index and other wing traits a...

A multitrait selection index (I T ) for Zimbabwean Jersey cattle was constructed. The breeding objective was defined in terms of production and functionality traits. The production component of the index included milk yield (M), butterfat yield (F), protein yield (P), butterfat percent (F%), and protein percent (P%), while the functional component included the somatic cell count (SCC). The inde...

Did global income inequality rise or fall over the past twenty years? Exchange rate comparisons suggest that inequality has risen, but the purchasing power comparisons of the Penn World Tables suggest inequality has fallen. We show that both measures are biased. Exchange rate comparisons ignore the relative price of non-tradables, whilst the Penn World Table method of calculating purchasing pow...

Epidemiologists are often interested in examining the effect on a later-life outcome of an exposure measured repeatedly over the life course. When different hypotheses for this effect are proposed by competing theories, it is important to identify those most supported by observed data as a first step toward estimating causal associations. One method is to compare goodness-of-fit of hypothesized...

Multi-Trait Selection of Promising Advanced Lines Rapeseed Using Index Ideal Genotypes

Myside bias occurs when people evaluate evidence, generate evidence, and test hypotheses in a manner biased toward their own prior opinions and attitudes. Research across a wide variety of myside bias paradigms has revealed a somewhat surprising finding regarding individual differences. The magnitude of the myside bias shows very little relation to intelligence. Avoiding myside bias is thus one...

Abstract. Suwarti, Ghulamahdi M, Sopandie D, Trikoesoemaningtyas, Sulistyono E, Azrai M. 2022. Secondary trait and index selection determination for maize genotype in acidic tidal swamp environment. Biodiversitas 23: 4169-4179. Determining secondary traits as complementary genotypes abiotic stress environment is compulsory since yield-based usually provides biased result. This study aimed to ob...
