Sure! Let's talk about hox genes and how they help living things grow!

**Similarities:**
1. **Blueprint for Body Plan:** Hox genes in both mice and fruit flies act like a set of instructions or a blueprint that tells the body how to build itself. They help decide where different body parts go, like legs, eyes, and wings!

2. **Order Matters:** In both mice and fruit flies, the order of the hox genes is very important. The genes at the front of the DNA tell the body to make parts at the head, while genes further back tell it to make parts towards the tail. So, they work in a neat line that helps organize the body.

**Differences:**
1. **Body Size and Complexity:** Mice are much bigger and more complex than fruit flies. So, they have more hox genes than fruit flies, and those genes help make more complicated body parts, like arms and legs, while fruit flies have simpler parts, like wings and legs.

2. **Different Body Parts:** Hox genes in fruit flies are responsible for making things like wings and antennae, while in mice, they help form things like spine and brain structures. So, even though the basic idea is the same, the specific body parts they help create are different.

In summary, hox genes are like a guide for building bodies in both mice and fruit flies, but mice are more complicated with more parts compared to the simpler fruit flies!
