Solution

The correct option is A $10 g$
The genotype aabbcc is considered as homozygous recessive genotype, the genotype AABBCC is considered as homozygous dominant genotype.
The total number of alleles in each genotype is 6. The value of homozygous dominant is 160 kg, the value of homozygous recessive is 100 kg. The difference of these two values is divided by total number of alleles in each genotype to find out the contribution of each polygene as in the image.
So the, correct option iis '10 kg'.

Q. The students of Class XII are going on a trek to Gangotri. They have to pack their bags for six days and keep them light. They also have to take things that do not take too much space. So they will look for things that have both less volume and less weight. After all, they will carry their own bags while climbing the mountains!
They even dry the onions and tomatoes to make them light. One kg of onions or tomatoes becomes 100 g when the water inside dries up.
