Humans have 23 pairs of chromosomes. Each chromosome in pair is homologous to another one in pair.
Does this imply, that the entire chromosome in any cell is obtained from only one parent? I mean entire single chromosome from one parent, and entire homologous one -- from another parent?
This is obviously true for sex chromosomes, especially in boys. They get Y from father and X from mother.
Is similar true for any other pair of chromosomes?
Or they are exchanging genes during mitosis too?
I.e. parents data is distributed grouped by chromosome or by gene?
