How much ';mixture'; is usual when recieving parent's dna?

For example a person recieves 50% of genes from mother and other 50% from father. Or is it that usualy, a person recieves 90% of genes from one of parents? Hope I make sense.How much ';mixture'; is usual when recieving parent's dna?
A human female gets half of the genes from each parent including the sex chromosomes where she gets one X chromosome from each parent.





A human male gets more than half from the mother. The male gets a small Y chromosome from the father and a larger X chromosome from the mother.





For the other autosomal chromosomes, all of the offspring will normally get the same number from each parent.





However there are some genetic disorders where the offspring will get more or less than the correct number of chromosomes. One example is Down syndrome where the offspring gets two copies of chromosome 21 from the mother and one chromosome 21 from the father.How much ';mixture'; is usual when recieving parent's dna?
You receive 50% from each parent because you receive one copy of each chromosome from each parent
