In humans, each cell nucleus contains 23 pairs of chromosomes, a total of 46 chromosomes. The first 22 pairs are called autosomes. Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The 23rd pair of chromosomes are called allosomes.
A human egg contains only one set of chromosomes (23) and is a haploid. Sperm also have only one set of 23 chromosomes and are therefore haploid. When an egg and sperm fuse at fertilization, the two sets of chromosomes come together to form a unique diploid individual with 46 chromosomes. [2]

That could be considered gender non-conforming, since nail polish is typically attributed to female-presenting people in our society. Or, on a larger scale, the person might not choose to identify ...
The authors differentiate between sex differences, caused by biological factors, and gender differences, which "reflect a complex interplay of psychological, environmental, cultural, and biological factors".

In cultures where the gender binary is prominent and important, transgender people are a major exception to the societal norms related to gender. [3] Intersex people, those who cannot be biologically determined as either male or female, are another obvious deviation. Other cultures have their own practices independent of the Western gender binary.
