Say, one has prepared bismuth nanoparticles using plant extract without the necessity of adding NaBH4, will there be Bi NPs or Bi2O3 NPs?

NPs= Nanoparticles NaBH4= Sodium Borohydride Bi= Bismuth Bi2O3= Bismuth Oxide A further question, without calcination. The person does not do any calcination.

Wosene Gebreselassie Abtew

Dear Gopal

F2 derived RIL are appropriate for linkage mapping. GWAS is done on natural population preferably more than 300 genotypes.

Best,

Pramod Sargar

If you have only a single population, the linkage-based QTL mapping would be method of choice. If you have more than one population, and some other inbreds along these RILs that are genotyped, GWAS would be better choice.

Sanjay Kumar Sanadya

If you have two or more RILs populations derived from different parentages then can be conducted GWA study.
