2. Morran et al. 2011 tested the Red Queen Hypothesis with an experiment on populations of the roundworm Caenorhabditis elegans. Populations of C. elegans include both males and "hermaphrodites" (individuals capable of producing both male and female gametes). Hermaphrodites can reproduce alone (termed selfing i.e., asexual reproduction) or mate with males (termed outcrossing i.e., sexual reproduction). The rate of outcrossing in a population can be used as an index of how much selection is favoring sexual reproduction (outcrossing) over asexual...
please help with the graph! I am having a hard time doing it ! NATIONAL CENTER FOR CASE STUDY TEACHING IN SCIENCE Part IV-An Experiment A team of scientists at the Imperial College London tackled the pro tre magazine (March 25, 2005). They decided to use veasts, which are can reproduce both sexually and asexually, are easy to keep in the lab casts normally reproduce asexually, but when they are stressed (starved, high temp reproduce sexually.

need help with this .. From the pages 571-587 attached below. 1a) Suppose a population of guppies was infected with a parasite. In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection. A subsequent mutation in the parasite results in a genotype that is unaffected by the newly evolved resistant guppy genotype. What is the name of the hypothesis that explains this host parasite “arms race”.? 1b) What is this name...
