Why do we look like our parents and siblings? What is a species? How are organisms adapted to suit their environment? What is a gene? Plants have been used for centuries to help answer these and other similar intriguing questions. Whether we are talking about natural selection, inheritance, the discovery of genes that can jump, or about one of the first multicellular organisms to have its entire genome sequenced, it is to plants that we must look. This course will take you on a journey through the major discoveries in genetics that have relied on the brilliant and fascinating world of plants, we will discuss why plants have proven so vital to this work, as well as explaining what we mean by terms like genetics, genome and chromosome, amongst others.
