A Lion male bred to a Tiger female produces a Liger. It is larger than either parent species because a Lion male’s DNA sends signals to the female to maximize maternal investment (Lions compete sexually) while the Lion female’s DNA tends to blunt this signal.

A Tiger female pregnant with a Liger isn't prepared to deal with this the same way a Lion female is - and maternal investment is way out of whack - resulting in a HUGE cub that grows into a HUGE Liger.

A Tiglon, by contrast is from a male Tiger bred with a Lion female - they are smaller than either parent species because the Lion female is blunting the signal it isn't receiving at the same level from the Tiger male’s DNA contribution.

This is a very common occurrence when you mix a promiscuous species involved in an evolutionary arms race between male and female with a non-promiscuous species that is more ‘peaceful’ in it's DNA.

Thanks; makes perfect sense.
