Drift effects on the multivariate floral phenotype of Calceolaria polyrhiza during a postglacial expansion in Patagonia
(Wiley Blackwell Publishing, Inc, 2016-05)
Quaternary environmental changes substantially impacted the landscape and promoted rapid evolutionary changes in many species; however, analyses of adaptive phenotypic variation in plants have usually neglected the underlying ...
DNA (ADN)
(2017-09-01)
The DNA (Deoxyribonucleic Acid) is the molecule where the genetic information is codified. The sequences of different nitrogenous bases causes differences in the genomic expression, causing variance in the organisms. There ...
Variances of direct genetic effects, maternal genetic effects, and cytoplasmic inheritance effects for milk yield, fat yield, and fat percentage
(Amer Dairy Science Assoc-adsa, 1998-02-01)
Milk yield, fat yield, and fat percentage during the first three lactations were studied using New York Holsteins that were milked twice daily over a 305-d, mature equivalent lactation. Those data were used to estimate ...

Evolutionary transition between bee pollination and hummingbird pollination in Salvia: Comparing means, variances and covariances of corolla traits
(Wiley Blackwell Publishing, Inc, 2019-04)
Covariation among traits can modify the evolutionary trajectory of complex structures. This process is thought to operate at a microevolutionary scale, but its long-term effects remain controversial because trait covariation ...
A phylogenetic approach to determining the importance of constraint on phenotypic evolution in the neotropical lizard Anolis cristatellus
(Evolutionary Ecology Ltd, 2017-01-01)
Question: Is the pattern of phenotypic divergence among populations influenced by constraint in the form of the genetic covariances among characters? Background: Quantitative genetic theory predicts that when evolutionary ...
