Explanation:
the key element in the ecological concept of species is that individuals within a species can successfully interbreed and conceive healthy offspring
<em>zygote</em> is the diploid cell that results from the fertilization between an egg and sperm
<em>sperm</em> is the male reproductive cell that is responsible for a baby to born
They are identical because they are made up of the same materials. we had one cell to begin with, and it didn't so much as clone itself, but split in half to creat 2 daughter cells. ther have the same plasma, same organelles, and most importantly, the same dna in their chromosomes so that when they grow, they grow exactly the same way.
