a. Are reproductively isolated

b. Are potentially capable of exchanging genes

c. Exchange genes across the pacific ocean

d. Have different evolutionary ancestries

e. Have formed a large hybrid zone

Answer: b. Are potentially capable of exchanging genes

Explanation:

Ginko tress are deciduous tress and unique from other tress with some special features. Some of the characteristics of ginko tress are - They have fan-shaped leaves and they are able to tolerate many urban conditions including air pollution, heat, confined spaces, and salt and they are easy to establlish.
