Free B1–B2 English Worksheet PDF: Designer Babies and Choosing Children’s Genes

Download this free B1–B2 English worksheet PDF for English learners and teachers. This lesson explores designer babies, embryo screening, genetic testing and whether parents should be allowed to choose certain characteristics for their children.

The article explains how some companies are offering parents more information about embryos created through IVF. Families may be able to identify certain inherited conditions and choose an embryo that is less likely to be affected.

Students also learn the important difference between screening embryos and changing their DNA. The article makes clear that screening compares existing embryos; it does not allow parents to design a child or guarantee characteristics such as intelligence, height or future health.

The worksheet looks at why newer genetic predictions remain controversial. Many traits depend on hundreds of genes as well as upbringing and environment, and medical experts have raised concerns about presenting uncertain predictions as if they were definite facts.

The article also explores the ethical questions behind the technology. Supporters argue that screening could reduce suffering and give parents more choices, while critics worry that access may come down to money and allow wealthier families to buy services that others cannot afford.

Students are encouraged to discuss where society should draw the line between preventing serious inherited disease and selecting preferred traits, as well as how much confidence people should place in predictions about a future child.
