Are we underestimating the genetic variances of dimorphic traits? 

Wolak, Mathew E.; Roff, Derek A.; Fairbairn, Daphne J. (2022-09-16)
Populations often contain discrete classes or morphs (e.g., sexual dimorphisms, wing dimorphisms, trophic dimorphisms) characterized by distinct patterns of trait expression. In quantitative genetic analyses, the different ...

Direct and indirect genetic and fine-scale location effects on breeding date in song sparrows 

Germain, Ryan R.; Wolak, Mathew E.; Arcese, Peter; Losdat, Sylvain; Reid, Jane M.; 0000-0002-7962-0071 (2020-04-02)
1. Quantifying direct and indirect genetic effects of interacting females and males on variation in jointly expressed life-history traits is central to predicting microevolutionary dynamics. However, accurately estimating ...

Is Pairing with a Relative Heritable? Estimating Female and Male Genetic Contributions to the Degree of Biparental Inbreeding in Song Sparrows (Melospiza melodia) 

Wolak, Mathew E.; Reid, Jane M.; 0000-0002-7962-0071 (2021-07-29)
The degree of inbreeding expressed within populations can profoundly shape evolutionary dynamics. The degree to which individuals inbreed is frequently assumed to evolve in response to selection, for example, resulting ...

nadiv: an R package to create relatedness matrices for estimating non-additive genetic variances in animal models 

Wolak, Mathew E.; 0000-0002-7962-0071 (2019-09-15)
1. The Non-Additive InVerses (nadiv) R software package contains functions to create and use non-additive genetic relationship matrices in the animal model of quantitative genetics. 2. This study discusses the concepts ...
