Final answer:
The gender with a pelvic bone greater than 90 degrees is female, with a wider subpubic angle, wider sacrum, and a broader greater sciatic notch to facilitate childbirth.
Step-by-step explanation:
The gender that has a pelvic bone greater than 90 degrees is female. The female pelvis has evolved to accommodate childbirth, resulting in a wider configuration, compared to the male pelvis. A distinguishing feature is the subpubic angle, which is broader in females, being greater than 80 degrees, while in males, it is usually less than 70 degrees. Additionally, the female sacrum is wider, shorter, and less curved than the male sacrum, contributing to a rounder pelvic inlet, which is more oval as compared to the heart-shaped inlet found in males. The female pelvis also boasts a broader greater sciatic notch and a wider and more shallow lesser pelvis, making it distinctively different from the male pelvis.
