Chapter 24, Problem 9TYPSS

Summary Introduction

To review:

The inappropriateness in the two statements mentioned in the problem regarding the apple maggot flies.

Introduction:

The preference of the apple fruit scent by the apple maggot flies can be accredited to two possible reasons mentioned below:

The presence of the alleles in the apple maggot flies to generate a response to the apple scents (stimulus).

The alleles, for the perception of specific scents, are inherited, which cannot be changed by the individual of the species.

A friend says that apple maggot flies prefer apple fruit scents because flies required these scents in order to survive. Another friend agrees and adds that the flies acquire the ability to distinguish the apple scents by spending time on the fruit, and this is the reason flies offspring prefer apples.
