Can conjoined (Siamese) twins be dizygotic twins in light of the theory that conjoined twins result from incomplete division of the embryo?

Summary Introduction

To determine: Whether conjoined (Siamese) twins can be dizygotic twins in the light of the theory that conjoined twins result from the incomplete division of the embryo.

Introduction: The twins are categorized into two types-monozygotic (MZ) twins and dizygotic (DZ) twins. Monozygotic twins are known as identical twins, whereas dizygotic twins are known as fraternal twins.

Explanation of Solution

Monozygotic twins are formed when a single egg is fertilized by a single sperm, which gets separated into two embryos during the early stages of development. These twins have the same genotype, same gender, and also carry the same genetic markers. Conjoined (Siamese) twins are the type of twins who are born by being physically connected to each other. These twins are formed when the embryo splits partially to form two individuals.

Dizygotic twins originate when two eggs ovulated in the same ovarian cycle are fertilized independently by two different sperms...
