<span>google/wiki In population genetics, the founder effect
is the loss of genetic variation that occurs when a new population is
established by a very small number of individuals from a larger
population. ... In the figure shown, the original population has nearly

Answer:
a. normally leads to formation of head structures.
Explanation:
- The product of the bicoid gene is a protein that is responsible for establishing the anterior-posterior axis during the embryogenesis phase of Drosophila development.
- The bicoid protein is localized at the anterior end of the egg of the drosophila and the anterior end it represses the expression of the mRNAs that are translated at the posterior end and helps in the expression of only anterior genes due to which it plays an essential role in the formation of anterior structures and thus the head of the fruit fly.
- <em>Therefore, from the given question it is very clear that since the absence of anterior larval body parts occurs in the absence of bicoid mRNA, bicoid must be specifying the head structures. </em>
