Would A Male Lion Mate With His Mother, Sister Or Daughter?

The social behavior of lions is a complex one and very unique from a lot of other big cats.

Rather than living solitary lives, lions form large groups known as a pride that usually contains several female lionesses and typically just one dominant male. 


However, most lions and lionesses in a pride are related – and this means  that there is a high risk of inbreeding. But do male lions willingly mate with their female relatives, including their own daughters? 

Here, we are going to be taking a closer look at the social dynamics of a lion pride and what this means when it comes to breeding and mating.

This way, we can answer the questions surrounding male lions mating with their female relatives to see just how likely this situation is in the wild. 

How Lion Prides Work

Before we answer the question surrounding males mating with their female relatives, we need to take a look at how lion prides work to understand our later answers. 

Like we said earlier, most lion prides generally consist of several lionesses with one male although it is not unusual to see up to four males in a single pride.

However, these lionesses are almost always all related to one another – they are all sisters, aunts, nieces, mothers, daughters and cousins to one another.

This is because a lioness will stay with her birth pride for her whole life, although some females may leave and become nomadic. 

However, the average lioness will stay with her birth pride, surrounded by her female relatives. 

Male lions, however, are a different story. 

Once they reach maturity, male lion cubs are ousted from their birth pride and forced to find somewhere else to live. A few males may leave at the same time, forming a coalition as they leave to seek out a new pride to take over.

They will then attack the male lion of another pride, killing them and any young cubs they have sired, so they can replace him as the dominant male of the pride and breed with the lionesses there. 

This is a natural instinct in the lions to avoid inbreeding. While female lionesses will stay with their birth pride and female relatives for the rest of their lives, male lions will not.

They will seek out a pride of their own with female lionesses they are not related to so they can mate and sire their own cubs. 

Will A Male Lion Mate With His Female Relatives?

Will A Male Lion Mate With His Female Relatives?

Due to the social dynamics and the group organizations of lion prides, it is very rare that a male lion will ever stay with their birth pride and mate with their female relatives – however, it is not impossible. 

Sometimes, male lions will accidentally mate with female relatives. Perhaps they take over a nearby pride once they have been ousted and the lionesses there are actually their cousins and aunts from their father’s side – this is a possibility.

However, male lions usually roam for miles and miles seeking new territory so again, this is still an unlikely possibility. 

A male lion will probably never mate with his mother or sisters because once he reaches maturity, he will be ousted from his birth pride before he has the chance.

If the male lion somehow overthrew his father, then he would take his place and win the right to breed with his close female relatives – but the likelihood of a very young male being able to overthrow his father, who will also have the support of the lionesses, is very, very slim. 

But the natural instinct of lions (just like all animals) is to breed and if there is an available female nearby, a male lion will not reject them just because they are siblings or parent and offspring. 

So, will a male lion mate with his mother, sister or daughter? The answer is yes – but because of group organization in prides, the likelihood of a male lion ever getting the chance to do this is super unlikely. 

The same goes for a lion mating with his daughter. As his female cubs grow older, they do become a part of the pride and will remain there for the rest of their lives.

However, this also means that the only male they can breed with once they reach sexual maturity is their father – but the likelihood that he is still in charge of the pride is also unlikely. 

Female lionesses take five years to fully mature and in this time, nomad male lions ousted from other prides will be challenging the father lion again and again.

It is likely that in this period, the father lion will either be killed or ousted from his own pride. His daughters will either be killed if they are too young to breed, or become the ideal mating partners for the new dominant male. 


So, a male lion mating with his close female relatives (his mother, sisters and daughters) is a very unlikely event. 

In captivity, this situation is purposefully avoided as male and female  lions are carefully moved from zoo to zoo, ensuring that inbreeding is kept to an absolute minimum.

However, out in the wild, the likelihood of a male breeding with his close female relatives is much higher but still very unlikely. 

This is because male cubs are ousted from their birth prides (where their sisters and mother will stay) once they mature.

They will be forced to find an unrelated pride to take over, where the new male lion will be able to breed with the previous dominant male’s daughters or kill them if they are too young. 

This is a natural organization within prides to avoid inbreeding, ensuring the success of the species by preventing males from breeding with their close relatives.

If a male lion is fortunate enough to remain in the same pride for long enough for his daughters to sexually mature, then he will likely mate with them – but he is far more likely to be killed or ousted before this can happen.
