प्रश्न
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?
संक्षेप में उत्तर
उत्तर
In field A, the reason for parental trait in consecutive generations of the offsprings is self-pollination.
In field B, variation is seen to occur because of recombination of genes as cross - pollination is taking place.
