Bio 1108 Lab article Presentation Assignment 2Reema Patel 2/8/12The Evolution and significance of male mate choiceTerminology List:1. Operational sex ratio (OSR):It’s the ratio of sexually competing males that are ready to mate with sexually competing females. 2. PRR: Potential Reproductive Rates. The potential rates at which reproduction could occur. 3. Parental Investment: It is the time and energy that a parent takes and puts into their offspring’s future at the cost of the parent’s ability to invest in other components of their fitness. 4. Lability: easily altered.5.Intrasexual selection: an act in which males fight over dominance of females.6.Ejaculation: the ejection of semen from a male reproductory tract.Summary Questions:1.

By seeing what males will mate with which females we see what types of traits and genes can be potentially passed on and so forth. We also get to observe as to how males fight with other males, and who wins and why. When we observe mating patterns it helps us figure out how to make a species thrive. We can then use this information to our benefit by helping the species that are slowing dying out survive. 3. Future Research?As far as future research goes, they may want to show how the males are fighting with the other males. The article talks about parental care a lot.
