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?
थोडक्यात 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.
