Yes, but it's dependent on a lot of things. Some chromosomal areas are more important than others. In humans and other mammals, it also matters from which parent the DNA came from (paternal DNA is different from maternal DNA, but a woman will 'rewrite' her father's chromosomes when passing it on to her child and a man his mother's, etc). Any variation in these things could cause developmental disabilities. However, typically things like inversions and translocations and such do not have huge phenotypic differences, whereas things like triploidy or uniparental disomy (inheriting both copies of a chromosome from one parent) have a more obvious manifestation.
- joshgel 7y agoSorry this isn't accurate at all. We don't 'rewrite' any chromosomes. Sometimes during errors in replication changes occur, but these are random. They presumably happen approximately equally in both parents contribution to your DNA (though I don't know this to be 100% confirmed empirically).
- mjg59 7y agoNot in terms of primary sequence, but imprinting has an impact on expression and is parentally determined.
- tathougies 7y agoImprinting is a thing, and yes, the sex of the parent matters. A woman does not pass on a male imprinted version of her father's chromosomes. She passes on the female version. While methylation is not part of the 'genetic code', it is part of the DNA molecule, and it does impact genetic expression. Anyway, in your pseudo-scientific world, how do you explain Angelman and Prader-Willi syndrome? Please... the world must know.
