Azygote is the product of fertilization. the diploid zygotes of four different organisms all underwent in order to grow in size and in order to produce the four very different embryos.

The question is incomplete. It should contain options. Here is the complete question;

A) meiosis; mitosis

B) mitosis; differentiation

C) meiosis; differentiation

D) differentiation; specialization

The correct answer is B.

Explanation:

A zygote is formed when the sperm meets the egg during sexual reproduction. This is also known as the process of fertilization. From a single-celled zygote, multi-cellular organisms are developed. The zygote is the first stage of developing a genetically unique organism.

The zygote is made of genes from two parents and thus bearing two sets of chromosomes.

A common feature of the sexual reproduction of organisms is when haploid gametes join to produce a diploid zygote.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
