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.
The other is the X chromosome. Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers testis development.7,XYY syndrome (simply known as XYY syndrome) is caused by the presence of a single extra copy of the Y chromosome in each of a male's cells. 47, XYY males have one X chromosome and two Y chromosomes, for a total of 47 chromosomes per cell.
