Subject: multv. regression for allometry

Dear group members,
In allometry studies there is one independent variable (x:centroid size)
and more than one dependent variables (Y is a matrix for shape
parametres) and the model is as Y=a+bx. But as I know, one of the
assumptions of multivariate regression analysis is that, both the
dependent and independent variables must be multiple (Y=A+BX ) .
And the results of multivariate regression analysis in MorphoJ program
and SPSS are different (for tangent coord. and centroid size).
I dont understand this situation. What are your opinions about this topic.
