Twins and Genetics

Identical twins share the same genetic code and thus are natural clones. Because identical twins share all of their genes, it has been said that it is the environment—rather than genetics—that accounts for any differences between them. Twins can either be monozygotic ("identical"), meaning that they develop from one zygote that splits and forms two embryos, or dizygotic ("fraternal") meaning that they develop from two single eggs that are fertilized by two separate sperms. In a study design that...

Genetic Engineering Cutting Edge Science By C.A.L.A. Consulting What Is Genetic Engineering? Genetic Engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism. When a gene for a desirable trait is taken from one organism and inserted into another, it gives the recipient organism the ability to express that trait. An accent, click to edit the text inside.
