1.	Question : A pea plant homozygous for yellow round seed is crossed with its recessive parents. Calculate the phenotypic and genotypic ratio the help of checker board .
Answer» Solution :Law of INDEPENDENT Assortment : (1) The law of independent assortment states that two parents differing from each other in two or more pairs of contrasting characters are CROSSED, then the inheritance of one PAIR of characters is independent of that of the other pair of characters. (2)From the results of the dihybrid cross, it is obvious that the character of yellow colour of the seed is in no WAY linked with the round shape of the seed. SIMILARLY the green colour of the seed is not linked with the wrinkledshape of the seed. Thisis due to the fact that in the abovecross, the two pairs of characters segregate independently. otherwords, there is independent assortmentof characters during inheritance.
