In reply to: unscrew it from the base. There are no instructions on how to put the TV back on the stand. I took it off to put it on a wall mount. I just moved and want the TV back on the stand. I can easily put in the two screws on the top but the bottom two screws are impossible to line up and screw in.
The behaviour of this X chromosome in males is different from those in the female chromosome. The female chromosome has more working genes than the male one. It is known to have more than 1000 working genes while the male chromosome has less than 100. Of these 1000 working genes, 200 to 300 are gender specific while the remaining are shared across the two genders.
Mammals and Drosophila females have two X chromosomes: XX males have one X chromosome and one Y: XY These are the  sex chromosomes , all other chromosomes are called  autosomes . The sex with two different chromosomes is the heterogametic sex. The other is the homogametic sex. For the X chromosome then, female mammals and Drosophila have two copies of each gene on the X, but males have only one. Females can be homozygous or heterozygous, but males are hemizygous.
