: Most Labradors have bad hips because they are all descended from a small number of dogs. They don't have enough [[biodiversity]] to inherit better hips.
: There are so few [[panda]]s left in China there is very little [[biodiversity]]. That means if one of them has a genetic condition that makes them unhealthy, this condition will be passed on to most of the [[panda]]s in the next few generations, making it even harder for them to survive.
==Key Stage 4==
===Meaning===
[[Biodiversity]] is the amount of genetic [[variation]] within [[species]] and between different [[species]]. The more genetic [[variation]], the greater the [[biodiversity]].
===About Biodiversity===
: [[Biodiversity]] within a [[species]] is important to help a [[species]] produce [[health]]y and [[fertile]] [[offspring]].
: Greater [[biodiversity]] in a [[species]] means there will be greater [[variation]] in that [[species]]. If the [[ecosystem]] changes then a [[species]] with greater [[variation]] can [[evolve]] more quickly and the [[species]] is more likely to survive.
: If a [[species]] is reduced to close family members their [[offspring]] can be deformed or inherit genetic conditions.
