Butterfly
A butterfly is a mainly day-flying insect of the order Lepidoptera, which includes the butterflies and moths. Like other holometabolous insects, the butterfly's life cycle consists of four parts: egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly coloured...

Description

The Postman butterfly has large long wings with an orange stripe down each forewing. It is poisonous and has red patterns on its wings. They tend to look similar to the species Heliconius erato
Heliconius erato
The Red Postman is one of about 40 Neotropical species of butterfly belonging to the genus Heliconius. It is also commonly known as the Small Postman, the Red Passion Flower Butterfly, or the Crimson-patched Longwing.-Description:The species is remarkably variable in colour and form throughout...

. Two features found on the underside help to distinguish H. erato from H. melpomene—H. erato has four red dots where the wing attaches to the thorax while H. melpomene has three and the yellowish white stripe on the underside reaches the margin of the hindwing in H. erato but ends before reaching the margin in H. melpomene.

There are many forms of this butterfly. The geographical variation in patterns has been studied using crossing experiments and it has been found that the patterns are associated with a small number of genetic loci.

Amplified fragment length polymorphism
Amplified Fragment Length Polymorphism PCR is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Keygene, AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky...
