BI226 2009 Section 3: Mapping in N. crassa and fine structure mapping
• Tetrad analysis in fungi has provided much information about the
mechanism of crossing-over and gene conversion.
• The gene is a linear segment of DNA that is divisible by crossing-over.
• The units of recombination and the units of mutation are the individual nucleotides of DNA.
• Alleles can be placed into complementation groups by complementation analysis.
