A True breeding Wild type fly was crossed with a True breeding Mutant fly to produce a Heterozygous F1. An F1 female was then crossed to a Test male. The results of this cross are as follows: cn vg 4202; cn 458; rd 4258; rd vg 482; cn rd 28; Wild Type 276; vg 32; cn rd vg 264. Which Phenotypes represent the Parentals i. s., the non- Cross Over Phenotypes from the F1 generation

What happens when the cell copies its chromosomes

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.
