We all know that humans have 46 chromosomes. 23 paired chromosomes. out of them 22 pairs are the autosomes which define various charachteristics that we inherit. Last pair is called the sex chromosome. In woman the ovum is denoted by 'X' chromosome while in males there aretwo types of sperm 'X' & 'Y. the composition of the last pair in female is XX and in male is XY. so when the X ovum fuses with X sperm it forms a female embryo and if X ovum when fuses with Y sperm it forms male embryo. but surprisingly the sex ratio is decreasing at an alraming rate the reasons varied in various countries but the result will be the same extinction of homosapiens. So lets take an initaitive to spread awareness. spreading awareness doesnt always mean going on the roads and shouting. it can also be through various media such as the social networking sites, blogs etc. well the creativity is upto you but don't just take this as a lecture take it as a warning which taken lightly would seriously mean doom !
