Why must a mother's dna match that of her biological children? why would damian expect half of the children's dna to come from their mother? why not 30% of it? or 70% of the dna?

Answer :

Because each parent contributes to their child 23 chromosomes, so therefore each parent gives their child half of the DNA of the child.

It wouldn't be 30% or 70% because the balance of the chromosomes the parents contribute is always equal.

Meiosis is a type of cell division, in which the genetic material is halved so that fertilization will restore the diploid complement.

In humans, the baby is produced by the fusion of male sex cell (Sperm) and female sex cell (ova).

Male sex cells and female sex cells are produced by meiosis and they contain haploid number of chromosomes.

For example- In humans, the 23 chromosomes from the sperm pair with 23 chromosomes in the egg, forming a 46 chromosome cell.

So, a Child gets 50% of the chromosome from male parent and 50 % of the chromosome from the female parent.

Since the child gets half of the chromosomes from their mother, a mother's DNA match with that of her biological children.
