Bilateral Symmetry

A body plan in which organisms have body shapes that are mirror images along a central line, characteristic of many animals.

Developmental Regulatory Genes

Genes that guide the development of an organism's structure and function through regulation of other genes.

Pollination Efficiency

The effectiveness with which pollinators, such as insects or wind, transfer pollen from male to female plant structures, facilitating fertilization.
