1. the quality or capacity of being able to cross or be crossed; the degree to which something can be traversed or passed through
Usage: often used in biology and genetics to describe the ability of organisms to interbreed
2. in genetics and breeding, the ability of two organisms or varieties to produce fertile offspring when crossed
Usage: technical; biology

Examples

• The crossability of the river improved after the new bridge was built.
• Scientists studied the crossability of different plant species to develop hybrid crops.
• The terrain's poor crossability made the expedition more challenging than expected.
• Researchers assessed the crossability between the two dog breeds before breeding them.
• The crossability of the border region was restricted by natural barriers.
• In agriculture, crossability between wild and domestic varieties is crucial for genetic diversity.
