No their babies won't look alike.

<h3>Explanation:</h3>

Both the couples mentioned here i.e. Sally - Harry and Emily - Ken are both identical twins. So they have similar pairs of genetic setup. This was possible because they developed from same zygote.

But during gametogenesis, crossing over and independent assortment occurs which brings about variation in genetic setup among the offspring. And it's very less probable that same crossing over will occur between the gametes of these couples. So, their offsprings won't look same.
