The Effect of Birth Order on the Induction of Mixis in the Rotifer B. calyciflorus
The basis of sexual reproduction is a perennial topic of interest in evolutionary biology. The rotifer, Brachionus Calyciflorus, is an interesting system to compare sexual and asexual reproduction because it is cyclically parthenogenetic, meaning it alternates between generations produced sexually and asexually. By understanding the mechanisms controlling the timing of sexual reproduction in such organisms, we can better understand how natural selection determines the balance between asexual and sexual reproduction. In this study I look at the contributions of three related factors in determining the proportion of sexually reproducing daughters a female produces. This study aims to answer how birth order, days since mictic egg and generations since mictic egg and/or their interactions, best explains the patterns of mixis inducibility.
