INTRODUCTION
INTRODUCTION
The golden dart frog can be found all over from Nicaragua, Bolivia and the Atlantic forest of Brazil to the Pacific coast of South America (Grant T, Frost D. 2006).

Background
Background
Secrete poison toxins from dermal granular glands. (Grant T, Frost D. 2006).
People would use their poison in their blow dart guns for hunting (Grant T, Frost D. 2006).
Reproductive isolation allows for speciation between different types of dart frogs (Wang, I. Summers K. 2012).
Females with the yellow phenotype are more likely to mate with males with a yellow phenotype (Wang, I. Summers K. 2012).
The ideal habitat of larva are found in a ground level pool or slow flowing stream or body of water (Grant T, Frost D. 2006).

Data Analysis
Data Analysis
Researchers studied the color variation amongst the different species of poison dart frogs to see how populations have been shaped by sexual selection (Wang, I. Summers K. 2012).
This was done by collecting different colored frogs by dorsal color and size. Then they were separated based on age and gender (Wang, I. Summers K. 2012).
In figure 4, frogs being represented by red (closed dot) and yellow (open dot) dorsal color are clearly distinguishable between one another (Wang, I. Summers K. 2012).

Conclusion
Conclusion
Based on the results of the study it was shown that the courtship between males and females correlates to the color of the phenotype. The preference that was proven was that females would prefer males of their own color (Wang, I. Summers K. 2012).
Two out of every three males that choose yellow females encounter will be red. A yellow female would, therefore, have to sample more males than a red female to find a suitable mate of her own color (Wang, I. Summers K. 2012).
