Interestingly, h and CVA estimates are somewhat suggestive of lower levels of genetic variance for inter-landmark distances associated with head morphology (as opposed to those associated with the whole body).
Specifically, at similar temperatures to that of the high temperature treatment in this study, Simmons found lower levels of additive variance for testis mass (CVA = 7.18 compared to 14.23).
IBP, intra-bladder pressure; LIAP, lower intra-abdominal pressure; UIAP, upper intra-abdominal pressure; HOB, head of bed, IAP, intra-abdominal pressure; COVA; coefficient of variance; LLA, Lower level of agreement; ULA, Upper level of agreement.
Bastiaansen et al. [ 50] found similar response to selection for GBLUP and ABLUP but the former accumulated lower level of inbreeding and consequently higher genetic variance than the latter.
As it has been recently pointed out by Dowling et al. [ 65], studies examining genetic variance in the outcome of sperm competition have generally found lower levels of additive genetic variance than studies focusing on specific traits with a role in sperm competition.
Furthermore, farmers who reside in locations with lower levels of precipitation, higher variance, and skewness are more likely to irrigate.17 Similar results were found in related literature before.
Although the sea urchin Strongylocentrotus franciscanus has a longer generation time, a population genetic model predicted faster rates of adaptive evolution in sea urchins compared with mussels (Mytilus trossolus) because larvae of the latter possessed lower levels of additive genetic variance.
