Mendelian Principles, Gene Concept, Epistasis & Allelism

The gene "M' has 10 alleles, viz. My to Myo. How many genotypes are possible for the gene M with various allelic combinations?

In a genetic analysis experiment, the rust resistance gene was found to be completely linked with red glume color. The leaf rust resistant stock with red glume was crossed with contrasting leaf rust susceptible white glumed line. The F; plant between them was found to be susceptible and red glumed. The genetic nature of both the genes were found to be monogenic. In Fz population the likely frequency of susceptible red glumed plant will be

In a genetic analysis of resistant stock, the F, plant with contrasting susceptible parent was found to be resistant. The Fz population was segregating in a ratio of 13 resistant and 3 susceptible. The test cross will segregate in
