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.
21.1 Genetic factors and hormones that determine gender. Genetic factors: introduction. In the nucleus of every cell of his or her body, a human being has 46 chromosomes. 22 chromosome pairs (numbered from 1-22) belong to the autosomes and 1 pair to the sex chromosomes or gonosomes. They are denoted as X and Y. A female has two X-chromosomes and a male an X and a Y-chromosome.
