Question

Why do two children from the same parents have similar structures but different genetic traits?

The two children receive different combinations of genes from their parents due to meiosis and fertilization.
The two children receive the same chromosomes from each parent due to mitosis and cytokinesis.
The two children grow up in a similar environment but are exposed to different learning experiences.
The two children develop the same mutations in their DNA but do not express mutations that impact physical characteristics.

Answer 1

its not C or D its A or B tell me if u got it

Answer 2

has to do with the fact that each parent actually has two different sets of genes. And that each parent passes only half of their genes to their child. And that the half that gets passed down is random. All of this together ensures that each child ends up with a different, unique set of genes. Hope it helps!!
