Answer:
It means it disapear from the population during a certain time period
Explanation:
Lost allele often refers to fixed allele and it is a phenomenon when only one allele of a gene is present in the population. This event occurs usually as a consequence of a disaster, for example forest fire. After the disaster, only certain individuals survive with the fewer alleles that the initial population. Other alleles are lost.
It maintains its structure, and it acts as a stainer.
It is called <span>Incomplete Dominance</span>
<span>Around 2.4 billion years ago, the first photosynthetic organisms appeared and used inorganic matter like carbon dioxide and water to produce glucose, with oxygen released in the atmosphere. Because of this, oxygen levels rose; this is called the <em>Great Oxygenation Event</em><span><em>.</em> Through time, photosynthetic organisms evolved to live in land (now as plants). As concentrations of oxygen in the atmosphere became higher, marine animals evolved to utilize oxygen readily available from the atmosphere (rather dissolved in water) hence the evolution of marine animals to land animals capable of respiration in land. </span></span>
