Estimated heritabilities of DCDB tasks at puppy and adult timepoints using the population pedigree and the genomic-relatedness matrix. Heritability estimates range from 0.01 to 0.61, with the highest heritabilities observed for the metrics from the novel object and surprising events tasks in puppies and for human interest in adults. Estimates from the pedigree and genomic methods are relatively similar.

Phenotypes graphed and ordered by the amount of change between puppy and adult estimates. Using the pedigree, slight increases seen for retrieval score, unsolvable task, and cylinder detour; little change seen for human interest metrics, laterality index or strength, visual discrimination, warm-ups, auditory discrimination, or cylinder inhibitory control score. Slight decreases for gesture marker, spatial working memory, odour discrimination, gesture pointing, and novel object. A large decrease of over 0.4 for surprising events (the only one with non-overlapping credible intervals). Slightly different results for genomic-based analysis, still with most estimates staying approximately stable or decreasing slightly. Surprising events is again the phenotype displaying the largest change, a decrease of just under 0.4.

1) Some traits were highly heritable, while others were not, suggesting fundamental differences in the underlying biological mechanisms & genetic architecture.

2) Estimates mostly stayed stable or decreased across time.

3) Pedigree & genomic methods produced similar results.

watching #ILoveLA and immediately clocking the twins from the 7th Edition of the #BehavioralGenetics book. these twins are so famous to me.

First transfer of behavior between species through single gene manipulation Scientists strengthen brain cell connections to enable gift-giving courtship behavior in fruit flies.   Researchers...

[Research] 🧬🪰 Nagoya University scientists have genetically transferred complex courtship behavior between fruit fly species for the first time! By activating a single gene in neurons, they made D. melanogaster perform gift-giving rituals it never did before. bit.ly/4ltnhqL #BehavioralGenetics 🧪

Kiana Kasmaii on mate preference & past experience in social butterflies: learning to prefer a new mate type (2 vs. 4 spots) associated with transcription differences in the antennae, eyes & brain. Learned vs. innate preferences also have some shared signatures.

Katy Takumi on genetic integration of morphology & behavior in 3 generations of crickets: morphology and behavior were actually somewhat independent/modular, with limited connections between the modules. Morphology seemed more genetically constrained than behavior.
