If males encounter offspring with their vomeronasal organ, they are more likely to?
attack offspring

Block
!!!When females mate, accessory olfactory bulbs does?
develops
!!!Why does the accessory olfactory bulb from the omeronasal organ develops when a female mates with a specific male?
To induce pregnancy block when encountering familiar odours
