Find out why offspring look like their parents in this free KS3 Biology worksheet — no preparation needed, just download and use. Perfect as a lesson starter, homework task, or quick revision activity for students aged 11-14.

Heredity is the process by which features are passed from parents to their offspring through reproduction. This worksheet introduces the concept with accessible, confidence-building questions.

This taster resource contains three questions worth 13 marks in total: a multiple choice question on the scientific term for the young produced by reproduction; a 5-mark fill-in-the-blank passage covering reproduction, offspring, species, parents and life cycle; and a 6-mark short answer question asking students to explain why a tadpole does not look like its frog parents, even though it is their offspring. A full answer key is included.

Want more? The full 100-mark premium worksheet goes deeper into heredity and how features are passed from both parents to offspring, visible and invisible inherited features, variation between siblings, and why identical twins are the only exception. A complete lesson bundle combining the full worksheet and extension activities is also available on the iNewittAll TES store.

The accompanying YouTube video is Google Classroom ready — simply copy the link directly into your Classroom assignment.
