Abstract

Pollination is key for the survival and reproduction of plants. Subsequently, floral traits often diversify by natural selection to match specific pollinators or to be efficient at self-pollination within a flower. Uncovering what genetic factors are required for different pollination syndromes will help to understand how and why pollination ecology exists as we see it. To investigate this, I grew second generation (F2) crosses between two species of Monkeyflower, Mimulus cardinalis (large, red, hummingbird pollinated flower) and Mimulus parishii (small, purple, self-pollinating flower) and measured 11 floral, vegetative, and reproductive traits. In addition to analyses of phenotypic and genetic correlations among traits, I propose to use RadSeq (a method of genome sequencing) to genotype the hybrids and map the genetic loci underlying each trait.
