Y sperm can stay in womb for 36 hours after which it dies
A centrifuge can separate the heavier X-bearing sperm from the lighter Y-bearing sperm.
Yes, all male have sperm cell contain both a X and Y chromosome and female have only two Y chromosomeI just want to clarify that Sperm Cell contain X "OR" Y chromosome, not X "and" Y.

y wuld a girl hav SPERM. !!!
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
I dont know much about x or y sperm but i do know sperm can survive up to 72 hours my doctor told me that.
The tail of the sperm whips and forces the sperm forward. Y sperm are smaller, lighter and faster, X sperm are larger, heavier and slower but can keep going for longer. Y sperm are sprinters, X sperm are long distance runners.

Sperm have both x and y chromosmes and it would be immpossible to try and kill the y without killing the x
Chromosomally, no. However, the survivability of Y-chromosome versus X-chromosome sperm under differing environmental conditions must also be considered. Y-chromosome sperm seem better adapted to alkaline environments, whereas X-chromosome sperm better survive acidity. Also, the sperm could be sorted before in vitro fertilization (IVF).
Increase Y chromosome sperm? Can't happen, ONE X and ONE Y chromosome in each

Firstly, this could not naturally occur. Our chromosome complement comes from the combination of chromosomes in our mother's egg and father's sperm. The mother, being XX, always contributes an X to the egg. The father, being XY, contributes either an X or a Y to each sperm. When an egg and sperm fuse the resulting embryo must be either XX or XY. If we assume some artificial introduction of a Y chromosome to the embryo, we either could have YY (a Y replacing the X) or XYY (a second Y as well as the X). YY would not survive, as there are essential developmental genes on the X. XYY is viable, and occurs naturally if the sperm contains an extra Y after a problem in sperm production. It is often not detected as there are few physical effects. It is thought to occur in ~1:1000 boys.
No they can't because they need the x and y sperm that we need. They do not have that type of sperm.
they survive by eating mice and with the cocoa beans the y make their own chocolate drink but so different by the one we know.

The food you eat will have no effect on sperm determination.
