It's silly to say that something is "biological determinism" just because it points out differences between men and women. Almost all traits have a strong overlap between men and women, including mental/personality traits, but occupational choice tends to be driven by extremes at a personal level. In general, men and women are about equally good at math, but at the far right end of the bell curve, men outnumber women significantly. Steven Pinker cites in "Human Nature" that at 6'0, men outnumber women almost 2000 to 1. Height is one of the more substantial examples of sexual dimorphism, but study after study has found sexual dimorphism in mental traits as well. This doesn't mean people should be judged based on their group's characteristics (which would be biological determinism) but that group differences can be quite severe at the extremes.

It's worth pointing out that men also tend to outnumber women significantly at the far left end of most bell curves. Data appears to show that for many traits, men have higher variability of traits, possibly caused by the differing sexual selection strategies of men and women. (There is much more diversity among mitochondrial DNA than Y-chromosomal DNA, which is just one piece of evidence among many that a smaller number of males produce a disproportionate amount of the offspring.)
