Answer:
These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. In fact, all the plants on Earth incorporate symbiotic cyanobacteria. For some untold eons prior to the evolution of these cyanobacteria, during the Archean eon, more primitive microbes lived the real old-fashioned way: anaerobically. These ancient organisms—and their "extremophile" descendants today—thrived in the absence of oxygen, relying on sulfate for their energy needs. But roughly 2.45 billion years ago, the isotopic ratio of sulfur transformed, indicating that for the first time oxygen was becoming a significant component of Earth's atmosphere,
I believe that the probability of having an individual with attached earlobes will be 50%. Since the attached earlobes is recessive then its genotype will be (ee), for the unattached ear lobes the genotype will be EE, Ee. Therefore, mating between an individual with attached ear lobes (ee) and one with unattached ear lobes, heterozygous, Ee, the offspring will be; Ee, Ee, ee, or ee. Therefore; half of the offspring will have unattached ear lones (heterozygous) while another half will have attached ear lobes.
