Final answer:
The PHENICE method is used to determine sex in forensic anthropology by examining morphological features of the pelvis. In biology, sex is genetic, typically indicated by XX chromosomes for females and XY for males in mammals, influencing the development of sexual characteristics.
Step-by-step explanation:
The PHENICE method (Pubic symphysis, Hip bone, Epiphysis of long bone) is used in forensic anthropology to determine the sex of an individual based on skeletal remains, particularly when looking at the pelvis. When determining sex using the PHENICE method, forensic anthropologists look at morphological differences in the ventral arc, subpubic concavity, and ischiopubic ramus of the pubic bone, all of which can show distinct differences between males and females. The appearance of these bone structures can provide reliable indicators of sex, helping forensic experts to make informed assessments in their investigations.
Additionally, sex determination in biological terms is generally associated with the chromosomal configuration of an organism. For instance, in mammals, including humans, the presence of XX chromosomes indicates a female (homozygous) and XY chromosomes indicate a male (heterozygous). This genetic sex determination plays a critical role in an individual's development of primary and secondary sex characteristics.
