Designer Genes is an event based on genetics. This year Mendelian genetics and most things dealing with Dominant over recessive are out. Another major element to the event is molecular biology (introns vs. exons, mitosis/meiosis, leading/lagging strand).Make sure you know Transcription. translation, replication, Hardy Weinburg equilibrium ( p^2 + 2pq+ q^2 = 1, p+q=1), and the other topics in your rule book. For the 2006-2007 school year, the event will focus more on the molecular biology and biotechnology elements of genetics.
