Document Summary
Lecture 14 notes: examples of sex (recombination) without reproduction, and of reproduction without sex lizards both the females were getting ready to reproduce but were not engaging in sexual recombination. Bacteria reproduces by binary fission but there is no genetic recombination. Some trees are facultatively sexual and asexual: how recombination contributes to population genetic variation. This reshuffling of genes into unique combinations increases the genetic variation in a population. Decreases extinction: meanings of monoecious, dioecious. Dioecious we have separate sexes male and female. Monoecious are having male and female functions in one individual: difference between sequential and simultaneous monoecy. Sequential monoecious are organisms that are born one sex and then when they become large/old they switch to becoming the other sex (clown fish, born male and then becomes female) Simultaneous monoecious are organisms that have both sexes at the same time: examples and predictions of size-advantage model of sex change.
