Mustard was growing in two fields- A and B. While Field A produced brown coloured seeds, field B produced yellow coloured seeds.

It was observed that in field A, the offsprings showed only the parental trait for consecutive generations, whereas in field B, majority of the offsprings showed a variation in the progeny.

What are the probable reasons for these?


Pollination is a method of sexual reproduction in plants where pollen grains from the anther of one plants are transferred to the stigma of another.

  • Self Pollination occurs in plants with the same or genetically similar flower . It results in consecutive generations with the parental trait .
  • Cross Pollination occurs in plants with the of one flower with another flower . It results in new generations with variations in their traits


Hence, variation in parental trait is possible in case of Cross Pollination and not Self Pollination

  • In field A , since offspring showed same parental trait, it is Self Pollination
  • In field B , since offspring showed different parental trait , it may be case of Cross-Pollination
