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
3
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

‘Two white-flowered lines of sweet peas were crossed to produce F. The F; plants produce only red flowers. Random mating
among F; plants produced 192 plants, 106 of which had red flowers and 86 of which had white flowers. What will be the
expected frequency of red coloured F2 plants which will segregate in 3 red and 1 white coloured flower in Fz: generation
