Answer:
Both contain genetic material, in the form of DNA and/or RNA. Both of them can replicate, that is, produce more organisms similar to themselves. ... They require a host cell to carry out life processes, such as replication and carrying out genetic instructions, etc. Bacteria are relatively bigger in size than viruses.
The genetic code is considered universal because the same four nucleotide bases are used by all known organisms
The number of phenotypes produced for a given trait depends on how many genes control the trait. Anyhow, The distribution of phenotypes for a typical polygenic trait can often be expressed as a bell-shaped curve.
Many traits are controlled by two or more genes and are, therefore, called polygenic traits<span>. Each gene of a polygenic trait often has two or more alleles. As a result, one polygenic trait can have many possible genotypes and phenotypes.</span>
