To find a gene, you have to associate a phenotype with a genotype (e.g. all individuals with white flowers have a certain allele

). it is much harder to find genes that are involved in polygenic traits than it is to find the genes responsible for discrete traits. why? it's much more difficult to determine the dna sequence of alleles associated with polygenic traits. the alleles associated with polygenic traits are usually co-dominant. polygenic traits results from extensive gene by gene interactions, which makes finding individual genes difficult. it's harder to find one of the many genes involved in a polygenic trait vs. the only gene involved in a discrete trait..

Answer:

<em>The correct option is D) the rate of photosynthesis increases and then levels off.</em>

Explanation:

Photosynthesis can be described as the process by which plants make their own food from carbon dioxide and water by using light energy from the Sun. Oxygen is produced as a by-product of this reaction.

As we increase the intensity of light, the rate of photosynthesis also increases. But after a certain time, the reaction rate will level off as there might be enough food produced or the light energy might have caused the temperature to rise which would have caused the enzymes to get denatured.
