The allele would be called codominant
When a dominant and recessive allele exist in an organism, only the dominant allele will be expressed. Dominant allele always mask the recessive because the gene code a protein while recessive gene doesn't. When both gene code a protein, they will be codominant and both gene will be expressed. The result could be a mixed effect. In this case, the purple is mixed color of red and blue.
Conidia are fungus spores. Macrocnidia means that the fungus spores are complex and large. Microconidia are fungus spores that are smaller.
Photosynthesis still occurs but the amount of red pigment is greater than the amount of green pigment. The chlorophyll still absorbs light energy. The red leaves does not affect the process of photosynthesis.
