Why is the low weight of a starving beetle not inherited?
AGerm cells divide too slowly
BGerm cell DNA is unchanged
CGerm cells are not yet formed
DGerm cells cannot store fat
Answer & Solution
Correct answer: B. Germ cell DNA is unchanged
1. Germ cells are made in specialised reproductive tissue.
2. Starvation reduces the weight of the beetle but does not change the DNA of its germ cells.
3. Change in non-reproductive tissue cannot be passed to the germ cells, so it is not inherited.
