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
