(a) Which species would probably fare better in response to a pathogen that infects all Mimulus species? (b) Which species would fare better if a pathogen caused hummingbird populations to dwindle?

A pathogen is a type of microbe that is responsible for causing disease in other organisms. Pathogens can be bacteria, viruses, or other microorganisms that enter the host cell or body without permission, proliferate within it, and then disseminate throughout the body via a brust opening.

Sexually reproducing species will lead to genetic variability; it refers to the differences in DNA sequence seen in each human genome. All organisms are distinct due to genetic variation. Mutation, gene flow across populations, and sexual reproduction all contribute to genetic variation.

The process of cross-pollination is typically dependent on pollinating agents in plant sexual reproduction, whereas asexual reproduction is not. They do not require pollinators since they reproduce by budding and fermentation, so asexual reproduction is best for this.
