Answer is….drumroll please A
Reading background information because it gives ideas from the author himself.
The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. The biomolecular data used for such calculations are usually nucleotide sequences for DNA or amino acid sequences for proteins.
Explanation:
Answer: Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.
Explanation:
A germline mutation is the mutation in the germ cells (of the fully developed sperm and ovum) of the parents. When the affected parents undergoes with the sexual reproduction the mutations are passed from the parents to the offsprings. When either the mutated oocyte or mutated sperm meet to form a zygote the precursor of new life. Thus few mutations are inherited by sexual reproduction than by asexual reproduction.
Punnet squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald Crundall Punnett, a mathematician, came up with these in 1905, long after Mendel's experiments. Let's take a look at how Punnet squares work using the yellow and green peas example from im not sure about the tree by three thing but maybe this will help :)
