The larvae of some insects are merely small versions of the adult, whereas the larvae of other insects look completely different from adults, eat different foods, and may live in different habitats. which of the following is most directly involved in the evolution of these variations in metamorphosis?
a) artificial selection of sexually immature forms of insects.
b) changes in the homeobox genes governing early development.
c) the evolution of meiosis.
d) the origin of a brain.

B. changes in the homeobox genes governing early development.

Explanation:

There are certain groups of genes that participate in the early stages of the development of all animals, these genes are called Homeobox, which determine what will be "anterior", "medium" or "posterior." Some mutations in Hox genes cause one segment to acquire the characteristics of another (homeotic mutations).

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
