CLASS 12 (PLUS 2) BOTANY: QUESTIONS & ANSWERS CLASS 12 (PLUS 2) ZOOLOGY: QUESTIONS & ANSWER The law specifies that 'when two pairs of characteristics are mixed in a hybrid, the segregation of one pair of characters is independent of the other pair of characters.' Two new combinations are produced in Dihybrid cross, round green & wrinkled yellow due to an independent assortment of seed color, i.e. yellow and green and seed shape. 1 Answers. Law of independent assortment is based on dihybrid cross. It states that inheritance of one character is always independent of the inheritance of other characters within the same individual. In other words, if the inheritance of more than one character is studied simultaneously, the factors or genes for each character assort out. The law of independent assortment also indicates that a cross between yellow, wrinkled (YYrr) and green, round (yyRR) parents would yield the same F 1 and F 2 offspring as in the YYRR x yyrr cross. The physical basis for the law of independent assortment also lies in meiosis I, in which the different homologous pairs line up in random orientations
