Question

Scientific Skills Exercise: Using Positive and Negative Correlations to Interpret Data Species with which type of reproduction would probably fare better in response to a pathogen that infects all Mimulus species? Why? The asexually reproducing species; the branching nature of the population would increase the likelihood of a few branches having the traits necessary to avoid or counteract the pathogen. The sexually reproducing species; they produce the most seeds to avoid or counteract the pathogen. The sexually reproducing species; the genetic variability in the population would increase the likelihood of a few individuals having the traits necessary to avoid or counteract the pathogen. The asexually reproducing species; producing flowers and seeds saps energy away from the plant's efforts to avoid or counteract the pathogen. Species with which type of reproduction would probably fare better if a pathogen were to cause hummingbird populations to dwindle? Why? The sexual

Explanation / Answer

Part F: The sexually reproducing species exhibiting more genetic variability in population would increse the likelihood of a few individuals to gain the trait enabling to avoid or counteract the pathogen. Hence, option 3 is correct. This is because counteracting a pathogen depends on genetic trait that shows the resistance or susceptibility to a pthogen.

Part G: If pathogen affects the hummingbird populations, then the asexually reproducing species that does not depend on hummingbird population would fare better. Hence, option 2 is correct. This is because, when the pollinating agent is not available most of the plants are propagated through asexual reproduction.
