Plant height of wild Solanum nigrum is controlled by polygene. A pure line plant with 60 cm height was cross to pure line plant having 20 cm height .All F1 plant having uniform height 40 cm. F1 plant was allowed to self-fertilization to produced 4/64 proportional of F2 plant having height 20 cm . What is number of polygene governing plant height?
