Distilled water tends to be acidic and can only be recommended as a way of drawing poisons out of the body. Once this is accomplished, the continued drinking of distilled water is a bad idea. Water filtered through reverse osmosis tends to be neutral and is acceptable for regular use provided minerals are supplemented.
Genetically speaking, the gender of a baby is determined by the presence of the 'Y' chromosome (or the absence of it). If a Punnett square were to be drawn and a mono-hybrid â¦ cross carried out, you can see that the only chromosome the female (XX) can pass on is the X chromosome.

If one considers sex a trait, or set of traits, then it followed that sex is inherited. In 1905, closer study of meiosis revealed the chromosomal basis of gender. Scientists noticed an oddball pair among the homologous chromosomes lined up at the cell equator during reduction division.
