Answer:
the population is polymorphic.
Explanation:
Polymorphism is the discontinuous genetic variation that leads to the production of varying unique kinds or forms of individuals within the population of an individual species.
Take for instance, allelic polymorphism is seen in the presence of multiple alleles that is produced within the members of an individual species as in peppered moths, human blood groups, and two-spotted ladybugs.
We have different causes of polymorphism: polymorphism can be sustained by an equity among variation developed by new mutations and natural selection. Genetic variation might be due to frequency-dependent selection.
Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
Explanation:
<h3>Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA). Organisms grow by undergoing cell division to produce new cells and replace older, wornout cells. During this cell division, DNA must remain intact and keep its even distributionthroughout the cells. Chromosomes are important to this process to ensure the DNA is accurately replicated.</h3>
