Witryna9 lip 2024 · An important goal of microbiome research is to determine the heritability of gut microbiome traits (1–8).Linking microbiome variation to host genetic variation can reveal which aspects of the microbiome are capable of responding to selection on the host, suggest which microbiome traits are under host control, and connect microbial … WitrynaNarrow Sense Heritability For a practical breeder, dominance variance cant be predicted, and it doesnt affect the mean or variance of the offspring of a selection cross in a systematic fashion. Thus, only additive genetic variance is useful. Breeders and other scientists use narrow sense heritability, h, as a measure of heritability. h = VA / VT

Witryna12 kwi 2024 · The lower heritability for CHIKV suggests that environmental or stochastic factors, as well as viral genotype, have a greater role than the mosquito’s own genetic factors in determining variation in load, at least in the tested population [68–70].
