Probability of getting both male and female trees when planting unsexed seedlings
The following assumes a 50% chance that any given seedling will be male or female in plant species with separate male and female plants. Note: There may be genetic issues within a specific species which result in a higher percentage of seed maturation from one gender or the other, but as a general rule it's safe to assume that a randomly selected species will be equivalent to a coin flip in terms of whether the resulting seedlings will be male or female. If you plant one single tree you have: a 50% chance of it being male a 50% chance of it being female If you plant two trees you have: a 25% chance both will be male a 25% chance both will be female a 50% chance you will get one of each gender If you plant three trees you have: a 12.5% chance all will be male a 12.5% chance all will be female a 75% chance you will get a mix of both genders If you plant four trees you have: a 6.25% chance all will be male a 6.25% chance all will be female a 87.5% chance you w
