Solution

The correct option is A B and C
The independent assortment of nonhomologous chromosomes during meiosis results in an independent assortment of two separate genes each of which carries an allelic pair. Thus, the factor for two traits (seed shape and seed colour here) should be present on two different nonhomologous chromosomes to assort independently and to produce parental (yellow round, green wrinkled) and nonparental combinations (yellow wrinkled, green round). Round, yellow and wrinkled, green seed traits are parental combinations as exhibited by first parent generation. Yellow seeds are round and green are wrinkled in the parental generation. The genes for seed shape and seed colour would have independently assorted during gametogenesis leading to the formation of new combinations i.e. wrinkled, yellow and round green. Thus, the correct answer is option B.
