Why all seeds of papaya cannot grow into plant?

Not all seeds of papaya can grow into plants due to several factors, including genetic variability, viability, and environmental conditions. Some seeds may be immature or damaged, while others may be unable to germinate due to unfavorable soil, moisture, or temperature conditions. Additionally, many papaya varieties are dioecious, meaning that only female plants produce fruit, so not all seeds will develop into fruitful plants.
