What is a fraternal twin?

a parasitic plant lacking chlorophyll and leaves and true stems and roots and reproducing by spores
Twins who develop from two separate fertilized eggs. They are genetically no more similar than brother or sisters but they have the same fetal environment
the combining of images from the two eyes to form a single visual percept
fuel consisting of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content

The correct answer is: Twins who develop from two separate fertilized eggs. They are genetically no more similar than brother or sisters but they have the same fetal environment

A is incorrect because it is describing a parasitic plant, not a human. C is incorrect because it is describing binocular vision, not twins. D is incorrect because it is describing fossil fuels, not human twins. Fraternal twins develop from two separate fertilized eggs, meaning they are not genetically identical like identical twins, but they do share the same fetal environment. This distinguishes them from identical twins who develop from a single fertilized egg and are genetically identical.
