In mendelian dihybrid cross, the ratio among homozygous dominant, pure heterozygous, and homozygous recessive traits in $F_2$ generation in pea plant is

Q. In a typical Mendelian cross, which is a dihybrid cross, one parent is homozygous for both dominant traits and another parent is homozygous for both recessive traits. In the $F_2$ generation, both parental combinations and recombinations appear. The phenotypic ratio of parental combinations to recombinations is

Q. In a Mendelian dihybrid cross, if one trait shows incomplete dominance and other trait shows homozygous dominant lethality then what will be the phenotypic ratio of progenies obtained in $F_2$ generation?

Q. Five Mark Questions :
(a) A true breeding homozygous Pea plant with green pods and axial flowers as dominant characters is crossed with a recessive homozygous Pea plant with yellow pods and terminal flowers. Work out the cross upto $F_2$ generation giving the phenotypic ratios of $F_1$ and $F_2$ generations respectively.
(b) State the Mendelian principle which can be derived from such a cross and not from monohybrid cross.

Q. In monohybrid cross, what is the ratio of homozygous dominant and homozygous recessive individuals $F_2$ generation?

Q. In a dihybrid cross where two parents (pea plants) differ in two pairs of contrasting traits, that is, pod color and pod shapes color, are crossed. Assuming that the male and female parent were homozygous dominant and recessive for both of these characters respectively, the number of green coloured pod among sixteen progenies of F2 generation will be
