Document Summary

Symbiosis/ symbiotic relationship is close and often long-term interaction between two or more different biological species. Mutualism any relationship between individuals of different species where both individuals benefit. Commensalism a relationship between two living organisms where one benefits and the other is not significantly harmed or helped. Parasitism one member of the association benefits while the other is harmed. Sexual reproduction involves the two alternating processes of meiosis and fertilization. Offspring does not resemble parent. happens to cnidarians. Parasites that must infect more than one host species to complete their life cycles. Aesexual reproduction mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which does not involve meiosis, ploidy reduction, or fertilization. The offspring will be exact genetic copies of the parent. Sexual reproduction process that creates a new organism by combining the genetic material of two organisms.

1. _____ Females that reproduce sexually versus asexually are said to incur a âtwo-fold cost of sexual reproduction.â Which of the following costs are associated with sexual reproduction for females?

A) MALES! That do-nothing lot really does not directly contribute offspring to the next generation. Females would be better off making all daughters.

B) FEMALES! In most natural settings, those daughters compete with their mothers for potential mates and resources needed to successfully reproduce.

C) MITOSIS! Since sexual reproduction can produce many more offspring than asexual reproduction, there are energetic costs associated with the mitotic divisions required to produce those offspring.

D) MEIOSIS! Every time a gamete is produced, the parent loses a little bit of itself. Half to be precise since only half of its genes are passed on to sexually produced offspring.

E) DIVERSITY! Mothers maximize fitness if all offspring are genetically just like them. Sexual reproduction causes genetic diversity, which ultimately lowers the fitness of both parents.
