what is the heterotroph hypothesis
The Heterotroph Hypothesis is the proposal that the first living organism was a HETEROTROPH. Before there were other organisms, they would feed on surrounding âleft-oversâ of their origin. There is evidence that the pre-life atmosphere and water environment was a reducing one, (no oxygen).
Heterozygosityâthe condition of having two different alleles at a locusâis fundamental to the study of genetic variation in populations. Indeed, Mendelâs original work was based on tracing the transmission to progeny of the two alleles present in heterozygous individuals at individual loci or combinations of loci.
