Working on a Dockerfile in order to build a WordPress image

I'm a newbie using Docker, and I don't understand something. If I'm using the official Dockerfile used to build the official Wordpress image, we start with: 

FROM php:5.6-apache

Then, to install extensions and models we have to use: 

RUN apt-get [install or Update]

My question is: Why we are using apt-get if we are not specifying in FROM that our image is a Debian based distro? Could I use yum?

The WordPress image Dockerfile does begin with FROM php:5.6-apache.

But the php:5.6-apache image Dockerfile starts with FROM debian:jessie.
Hence the apt-get.

Each image builds up based on another base image.
