Sexual selection was an idea proposed by Darwin and refers to the process in which males and females attempt to maximize their chances of reproductive success. Within a species there are certain characteristics that make individuals attractive to potential mates. An example of this is in peacocks‚ female peacocks are attracted to males with long brightly colored tails‚ even though this makes them easier to be spotted by predators. This characteristic then evolves within the species due to how males

Abstract: Having study natural selection and artificial selection we wanted to select for a trait on the plant Brassica rapa. We hypothesized that the leaf density is heritable and veritable. After our experiment we were able to conclude that our hypothesis was refuted because our average leaf density in our daughter population increased. Introduction: We are artificially selecting for a trait in the plant Brassica rapa. ( Wisconsin Fast Plant). Brassica rapa has been artificially selected

FEMALE MATE CHOICE IN POECILIA RETICULATA Abstract: In this experiment we examined female mate preference in the Trinidad guppy‚ Poecilia reticulata. Female guppies prefer to mate with brightly colored males in numerous species. From the jealousy experiment‚ the modeled female is jealous with the other female which is in the same section with 2 different males. The modeled female significantly preferred the males with 1 female than 3 males in other section. Introduction: Intrasexual selection

Option 5 Describe the difference between Darwin’s theories of (a) natural selection and (b) sexual selection. - Natural Selection The theory that members of a species each have slight variations from each other‚ and that these variations have the ability to enable some members of a species a survival advantage in certain environments. As a result of having a variation that increases their likelihood to survive‚ they are allowed to propagate‚ and their offspring have an increased likelihood of

Here we have some highlights of how the natural selection works and some of the evolutionary forces that drive evolution: The natural selection operates in base of the difference between de reproductive successes of the individuals. The genes of the most successful individuals (the ones that reproduces more) appears more in the next generation. If an individual cannot survive it will not be able to reproduce. Because of that natural selection is NOT RANDOM and can act really quickly. (Charlat et
