Answer:
Say the dominant gene is G, for free earlobes. Say the recessive gene is g.
We only need one G for free earloves to show. The possible genotypes are,
Gg and GG.
Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
The pathogen that cause is infection in bacteria
Here is the steps of the lysogenic cycle. Lysogenic cycle occurs only in temperate phages.
<span>1. After the phage attached to the host cell, it will then inject its own DNA. </span>
<span>2. The inserted DNA circularizes.</span>
<span>3. The DNA is integrated into the host cell DNA. This is done through recombination.</span>
<span>4. Each time the cell replicates, the prophage is reproduced together with the host DNA.</span>
<span>5. The prophage excise itself from the host DNA. But this is very rare.</span>
