it is a 50/50 mix of both your parents, plus recombinatioon during the last stage of meiosis (sex cells).
Also, all your mitochondria (power plant for your cells to function) come from your mother ONLY as sperms cells used up all their mitochondrial energy to reach the ovule. So in way you could say you have more "maternal" genetic material.
But unlike what Preachershoe said, mitochondrial origin have nothing to do with the passing on of sex related diseases. Those diseases are sex linked, meaning on either X and Y chromosomes.
Mitochondria have been used to date back generations and origins along a matrilieanar manner.
whether you look like your dad or your mom or your grandpa...is all a questioon whether the genes get expressed, and/or the recombination the genes under went prior to your "formation".

No. A child derives 23 chromosomes from each parent, for a total of 46. Sex is simply determined by chromosome placement, which is completely random.

Both males and females have more of their mother's genetics because mitochondria are 100% from the mother. This is why some diseases pass only through the mother.

No, every child is 50/50. Your sex is determined purely by chance. Your mother donates and X chromosome every time and your father either an X or a Y.

Nope it's 50-50 except for in terms of the sex chromosomes....sex-linked traits for males are determined by the mom since the dad just gives a Y chromosome but in that extent dad determines sex...in general 50-50 for normal traits...

I don't think so. I think it is still 50/50 from father and mother. However, you do inherit your y chromosome from your father... so that contains of of his genetic influence. There are some conditions, diseases, physical traits, etc that are associated with the y chromosome.

No, less. You have your mother's X, which has over 1000 genes, and your father's Y, which has only a handful of genes. However, some of your mother's genes were silenced in utero, especially facial structure genes:

Yes of course. Y haplotype carried from male to male in genetic history. you will have more activated gene from father. equal from both but activated different.
everyone here wrong. you get equal donation but not mean equal use. some gene favoured over other, some switch on more. this happen in male. mitochondria is a seperate organism this is irrelevent. this carried from other to daughter uninterrupted. Y haplotype is carried from father to son since original ancestor. mitochondria not that old. sorry.

No. I suppose as the Y chromosome is smaller than the X, you have more from your mother.
But, in reality, it is 50:50.

You get half from mom and half from dad. Mom has two XX's and gives you one. Dad had an X and a Y and gave you the Y since you are a boy, too. You are XY.
