A female astronaut from earth was on a mission to Jupiter.

There, she met a charming alien man. The two hit it off and decided to build a house in one

of the twelve moons of Jupiter and start a family. Just like us, the aliens of Jupiter have 46

chromosomes and identical DNA sequence and epigenetic mechanisms of gene expression.

However, they completely look different than us. They have giant ears and are twice our

size. Their gestation period is 12 months instead of 9 months (it is part of the biology of their

placenta and has nothing to do with the environment or size of babies). The astronaut and

her alien mate welcomed a baby girl into their family. Interestingly, the gestation period of

this baby was 12 months (despite developing in a human body). Moreover, she looked

nothing like her alien farther and rather looked more like her human mother (normal human

ears and regular human baby body size). Propose epigenetic mechanisms to explain these

observations

As this is science fiction, you can invent any mechanism you like. I suspect is is the delta rays emitted by invisible pink unicorns that are to blame.

Or is it homework?

It was homework but I was hoping to get other peoples thoughts. That's how you learn, not just by submitting and forgetting about it.
