Question

give F2 ratio of phenotype and genotype of a monohybrid cross​

Answer 1

The monohybrid cross involves the cross between plants considering only one trait. A cross between pure breeding tall (TT) and dwarf (tt) varieties gives all heterozygous tall (Tt) progeny in F1 generation. Selfing of F1 hybrid gives tall and dwarf F2 progeny in 3: 1 ratio respectively.

Answer 2

Answer:

As we saw last time, if we start with true-breeding parents (one homozygous dominant, one homozygous recessive), all of the F1 progeny will be heterozygous and show the dominant phenotype, and then these will give rise to a 3:1 ratio of phenotypes in the F2 generation in a monohybrid cross, and to a 9:3:3:1 ratio of .
