Create a Punnett Square. What percentage of the offspring will have yellow wings? and What is the phenotypic ratio (color ratio)?
Ww x ww= Ww, Ww, ww, and ww
50% has yellow wings
The phenotypic ratio is two white wings butterflies and two yellow wing butterflies 2:2 50%:50%

<span>Photosynthetic pigments, which absorbs the most sunlight is chlorophyll a.
This is the most abundant pigment in plants which absorbs visible light with wavelengths of 430nm( blue) and 662nm( red). It contains a hydrophobic phytol chain (in a lipid membrane) and a tetrapyrrolic ring (outside of the membrane) that absorbs the energy from light. At the centre of the structure is magnesium, Mg that can accept and donate e-.</span>
