Question

in the western united states, populations of an annual plant can be found almost continuously from san diego to seattle. even though individuals from the san diego and seattle populations never come into contact, they can still be considered part of the same species under the ______ species concept because they can potentially interbreed.
o reinforcement
o biological
o morphological
o lineage
o habitat

Explanation:

The biological species concept defines a species as a group of organisms that can interbreed and produce fertile offspring. Since the plant populations from San Diego and Seattle can potentially interbreed, they fit the biological species concept. Reinforcement is related to strengthening reproductive isolation. The morphological species concept is based on physical appearance. The lineage species concept focuses on evolutionary lineages. The habitat species concept is not a widely - used formal species concept in the same sense as the others.

Answer:

B. biological
