Umm no.. A woman carries the x chromosome, and the male carries the x and y.. And unless there was some kind of miracle that I dont know about a y and y chromosome can not in any way "mix together to make a child"... Now x and x can join together and create a baby which in turn would be a girl... Hope this made some since to you....

no. not naturally. And who knows what would happen if they did it in a lab.
Do a punnet square for a man and a woman. Women are XX and Men are XY.
so you get possible combinations of
XX or XY only. Since the woman doesn't carry a Y, you can never get 2 Ys
Maybe in the case of some genetic abnormality (such as the XYY male or the XXY male, tho I don't think the same thing happens to women, the presence of Y always creates a male)

No. Normally a child is XX female or XY male. Sometimes there is a chromosomal abnormality like an extra chromosome - XXY, XXX or XYY or a missing chromsome - XO. All those can be present in healthy adults some with only minor difficulties.
An abnormal egg with no chromosome could be fertilized with an abnormal sperm with YY. However, this would not be a viable pregnancy. There would be a miscarriage.

Not a viable one. In order to make a viable embryo, it must have at least one X (at least to create a normal fetus). If it had two Y chromosomes, I would think it would have to be a Chimera or some other extremely rare genetic occurrence like that. You would also need a way to combine them.
There has been some speculation in the past that Two female chromosomes will make a child, but not two male ones, and how women don't really need men in order to reproduce.

No. A woman is XX and a Man is XY.
The woman's egg would always come "equipped" with the X, and the man contributes either the x or the Y (therefore the man's contribution is actually what would determine the sex of the baby, not the woman)
There's no way a guy could contribute to Y's and the woman contributes nothing..... all genes/dna are comprised of 50% mother's and 50% fathers.

No. There are functions and genes on the X chromosome (which is much larger) which are necessary for human life. If, somehow, hypothetically, there was a deactivated egg with no functioning sex cells in it, and it was 'fertilized' by two Y-carrying sperm, nothing would happen. YY is incompatible with life.
Secondarily, you need to use a female germ cell because that is the cell carrying mitochrondria - sperm do not have it - and this is also necessary for life.

i dont think so..cuz the egg is always an x chromosone and the sperm can be either x or y so it decides the sex of the child...but ive never hears of a y-y pair

no it's imposable
you need the X from the female and the X or Y from the male to create a child. So the only possibilities are XX-female or XY -male.

Never, the female egg is ALWAYS an X-chromosome carrier, the male sperm provides and X to match to make a girl or a Y-chromosome to make a boy.

No. women are xx, men xy. Any combination of those will *never* produce a yy child, which would be a dual male chromosome.
