Chromosomes are long, string like aggregates of genes that carry heredity information. They are composed of DNA and proteins and are located within the nucleus of our cells. Chromosomes determine everything from hair color and eye color to sex. Whether you are a male or female depends on the presence or absence of certain chromosomes.
Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome.
Sex Chromosomes:
In human sexual reproduction, two distinct gametes fuse to form a zygote.
The male gamete, called the spermatozoan, is relatively motile and usually has a flagellum.
The female gamete, called the ovum, is nonmotile and relatively large in comparison to the male gamete.
Sex Chromosomes X-Y:
The male gametes or sperm cells in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. They are either X or Y. The female gametes or eggs however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male.
Timing and Position of Intercourse can influence the sex of child
Advice on using the timing and position of intercourse, eating habits and herbal remedies to influence the sex of your child is available everywhere from your mother's kitchen to the writings of the ancient Chinese. However, none of the methods have been scientifically proven to work.
One of the commonly known method is that of Dr. Landrum Shettles who concluded that sperm carrying the female chromosome live longer than those carrying the male chromosome. Anyone hoping for a girl should aim to have intercourse two to three days before ovulation; those hoping for a boy should plan intercourse the day before or on the day of ovulation. Frequent intercourse is advised for those hoping for a girl and ill-advised for any couple hoping to conceive a boy.
Sperm carrying the female chromosome are also more acidic than sperm carrying the male chromosome. A number of products have been developed for application during intercourse in order to deactivate unwanted sperm. For example, if a couple would like to conceive a male child the lotion would be more alkaline in order to neutralize the sperm carrying the female chromosome.
Other folk remedies say that acidic and salty foods help conception of a girl and hinder the conception of a boy, while caffeinated drinks are supposed to activate the male sperm if drunk right before intercourse. Another common tip is that doggy-style sex supposedly delivers the sperm closer to the egg - effectively giving the faster swimming male sperm a head start.Female Orgasms are also supposed to help the male sperm as secretions of alkaline mucus into the vagina give them favourable conditions over the acid-loving female sperm.
After all these ,In reality there is little you can do to influence the gender of your child;
Acidic Foods Include
sugar
beer
nuts and nut butters
cooking oils
Meat
Beans
Fish
birds
Buttermilk
Liver and other organ meats
Most fermented foods and aged cheeses
Broth made from bones or other animal parts
Alkaline Foods Include
wine
chocolate
tropical fruits-mango,banana ,citrus fruits
temperate fruits-apple,pear(perikai) ,almond(baadam)
potato
Eggs
watermelon
spinach
leafy vegetables
round vegetables
seeds
salt
Please note that some foods, such as citrus fruits, have an acid pH before they are consumed and but they usually leave an alkaline residue in the body after they have been metabolized.
Hard Water - Hard water is just the opposite of soft water. It is water that has a high mineral content, and as a result tends to be more alkaline. Some studies have shown that people have less heart attacks where the water is hard, presumably because the disolved minerals that make the water hard are important for nutrition.
Soft water - Soft water is water that is low in minerals. This type of water tends to be more acidic.
