In a Mendelian monohybrid cross, the F2 generation shows identical genotypic and phenotypic ratios. What does it tell us about the nature of allelesinvolved?Justify your answer.

Show the monohybrid cross between (RR) and (rr) and write the phenotypic and genotypic ratio of F_2 generation.

In the F2 generation of a Mendelian dihybrid corss the number of phenotypes and genotypes are :

Answer the following question What are F_1 and F_2 generations? Why are genotypic and phenotypic ratios different in these generations?

In dihybrid cross, F_2 generation offsprings show four different phenotypes whil the genotypes are...............

The phenotype and genotypic ratios in F_2 generation are idetical in a certain kind of inheritance. Name the organism in which it occurs and the interaction ivolved.

In Co-dominance and incomplete dominance genotypic and phenotypic ratios are identical. Explain how they diffe in their phenoypic nature in F_1 hybrids.

There are 16 possible individual in F_2 generation. Try and find out the phenotypes as well as the genotypic and phenotypic ratios.
