Gynodioecious Species Essay

801 Words 4 Pages
Objectives and Hypotheses The chief objective of the proposed dissertation is to study the gynodioecious breading system in a phylogenetic and ecological framework focusing on tree species of early angiosperms. Along the way, this involves several additional goals. Chapter 1. The first objective is to determine whether floral dimorphism is translated into gynodioecism in Lauraceae, the phylogenetic relationship with other breeding systems in Lauraceae. Results would provide steady evidence to define gynodioecious on Lauraceae as well to define the phylogenetic association with other mating systems in the O. complex.

H1: Gynodioecism is a reproductive system occurring species described in O.
H2: Dimorphic species described in the O. complex are result of gynodioecism
H3: Gynodioecious species belonging to the O. complex are related among them. Chapter 2. This chapter is focused in determining the association of morphological characters with gynodioecism in Lauraceae and the possible roll on

Different disciplines have add terms that can be used indistinguishing {Webb:1999jd} and the lack of standardization has resulted in a confusing terminology. An important contribution for the study of evolution of flowers occurred when the gamete production became more quantitative rather than qualitative measuring their contribution to the genes to the afterward generations at population levels {Lloyd:1972fw, Lloyd:1975ju, Lloyd:1976hd}, and the spatial or temporal development whiting or among individual (Figure 1.). The effect on models of reproduction, and the ecological impact on genes diversity within populations highly increased the number of studies about evolutionary transitions and polymorphism among mating systems in
