C. protein synthesis (they make proteins)
I think it’s phenotype bc phenotypes is what the natural selection acts on bc it’s what interacts with an organisms environment and not the genotype.
Gregor Mendel was an important scientist, considered to be the founder of the science of genetics. His experiments on the crossbreeding of plants and the passing down of favourable traits, led him to establish the laws of Mendelian inheritance. He was using pea plants for his experiments and he was studying seven different pea traits: pea shape and color, pod shape and color, flower color, plant size and position of flowers.
