gregor mendel used pea plants that were heterozygous for each of two traits—seed color and seed shape_to generate a
dihybrid cross. the phenotypic ratio of the resulting offspring was nine with round and yellow seeds, three with round and
green seeds, three with wrinkled and yellow seeds, and one with wrinkled and green seeds. from these results, what could
mendel conclude?

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
