Vedclass · Accepted Answer

Reduction in weight of the organism due to starvation is genetically controlled.

Vedclass · Answer

(A) The correct answer is $A$. $1$. Reduction in weight due to starvation is an acquired trait caused by environmental factors (lack of food),not by changes in the $DNA$ of germ cells. Therefore,it is not genetically controlled and cannot be inherited by the next generation. $2$. Option $B$ is correct because evolution is defined as the change in the frequency of alleles in a population over time. $3$. Option $C$ is correct because weight is a complex trait influenced by both genes and environment; thus,low-weight parents can produce heavy-weight offspring if the environmental conditions (nutrition) are favorable. $4$. Option $D$ is correct because only inherited traits (those present in the $DNA$ of germ cells) are passed to the next generation and contribute to the evolutionary process.
