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.
Deer
The family tabanidae consists of horse flies and other similar flies such as deer flies. So let's look at some distinguishing characteristics of both horse and deer flies.
Body Length: Horse flies are 10-30mm, Deer flies are 6-11mm.
Antennae: Horse flies have short antennae, Deer flies have long.
Ocelli: Horse flies have either vestigial, or entirely lack them. Deer flies have them.
Wings: Horse fly wings are clear, uniformly cloudy, or spotted. Deer fly wings are distinctly banded.
So on those three characteristics, Deer flies match all of them, while horse flies match none. So the answer is deer fly.
If the Grasshoppers go missing, then the mice will lose their food source and eventually die. Which means the snakes will also lose their food source, which is mice.
Light?
I think. Hope that helped.
