So you have two alleles for every one gene, and the chromosome is composed of 2 homologous chromatids that have one of the 2 alleles for the specified gene on each chromatid.
when you have to replicate that chromosome the way I understand DNA replication is is that you have a serious of functioning proteins that make a one-to-one photocopy of that entire chromosome. Despite the minor mutations poss. involved with DNA replication in general. But if I have a heterozygous diploid whose chromosome splits off, both chromatids should just replicate themselves. So the diploid cell will duplicate into 2 individual homozygous chromosomes. (I'm not trying to talk about meiosis right now, just talking about cellular division)
I'm sorry that these are massive run-on sentences
