Endler females mating preference for male guppies: A case study REKHA SATHYAN BIODIVERSITY AND CONSERVATION BIOLOGY UNIVERSITY OF THE WESTERN CAPE

Introduction Female mating preference *Basis of colours *Large and more chromatic orange spots

Continu ….. Findings shows female guppies of different strains prefer the same male colours (Houde 1987) Female guppies prefer more bright colours Females discriminate males on variation in the extend of orange pigment

Continu…. Female guppies prefer Dark colours  Especially red and black colours  Due to sexual signal

Approach Endler female guppies choice is different colours Several research has been done on the orange colour preference

Continue …… But here this study will be focusing on yellow and red top swords guppies Such as Top sword Metallica Top sword snake skin

Research question Would endler female guppies prefer top sword Metallica or top sword snake skin?

Hypothesis Female mating preference: Top sword Metallica is red colour Top sword snake skin is yellow colour Tail morphology is same

Methods Endler females (3 Endlers) in centre tank * 3 Top sword Metallica males in right tank * 3 Top sword snake skin males in left tank

Continu……… * Endler female should be yellow or black colour * Observe endler females direction of movement

Top sword Metallica Endler female Top sword snake skin Methods
