“…Similar results were described by Cardoso et al (2004) for Angus cattle and Toral et al (2011) working with Hereford and Hereford x Nelore cross animals. The high correlation between C and other traits can be attributed to aspects of conformation within the measurements of precocity and musculature (Cardoso et al 2004).…”

“…The high correlation between C and other traits can be attributed to aspects of conformation within the measurements of precocity and musculature (Cardoso et al 2004). These findings support that selection for one of these traits will also improve the other due to both pleiotropic effect and linkage in sets of genes that are responsible for the expression of C, P, and M (Toral et al 2011).…”

“…et al, 2004;Weber et al, 2009;Koury Filho et al, 2010;Queiroz et al, 2011;Toral et al, 2011); esses resultados sugerem que existe uma dependência genética entre os escores. Assim, a seleção para qualquer dos escores trará mudanças genéticas no mesmo sentido para os outros, dificultando a seleção de forma independente.…”

“…As pesquisas realizadas mostram que existe variabilidade genética nos escores visuais, o que permitira progressos genéticos quando feita a seleção para essas características (Jorge Júnior et al, 2001;Toral et al, 2011). As vantagens apresentadas na avaliação, como o baixo custo e a facilidade de implementação, permitem que um grande número de animais possa ser avaliado.…”

“…A grande maioria dos trabalhos que estimam parâmetros genéticos para as características de escores visuais usa modelo linear com estimação de máxima verossimilhança restrita, pela facilidade de aplicação e pelo menor tempo de processamento, quando comparado com modelos de limiar (Jorge Júnior et al, 2001;Araújo et al, 2010;Toral et al, 2011).…”
