Explanation:
BB=Brown as both are big B's
Bb=Brown as there is a big B
bb=Blue as both are little b's
When there isn't enough room in the cell for two complete molecules of DNA, the prokaryote stops replication and undergoes cell division.
These genes could have arisen by gene duplication.
<h3>What is gene duplication?</h3>
Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.
Gene duplication is a phenomenon that can happen through a variety of ways:
- Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
- Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
- Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Answer:
Option C
Explanation:
In elephant seals, the male arrive the beach first and start establishing its territory. Once their territory is established female elephant seals starts arriving at the beach and prefer mating with the male who can defend their territory or females in his territory from other males. All females in the territory of specific male mate with the male give birth to their pups and after staying for few months move back into the water.
hence, option C is correct
In this question we will do a Biological Classification History Check.
<h3>1. Binomial nomenclature</h3>
Binomial nomenclature or binary nomenclature designates the set of rules that regulate the attribution of scientific names to species of living beings.
<h3>2. Domain</h3>
Is based on molecular phylogeny data. According to Woese, there are three domains: Archaea Domain, Bacteria Domain, and Eukarya Domain.
<h3>3. Both focus on illustrating taxonomic relationships between organisms.</h3>
No, binomial nomenclature is for the purpose of assigning names.
<h3>4. domain, kingdom, phylum only.</h3>
No, the classification is more extensive
<h3>5. juglans nigra</h3>
It is a tree that can reach heights between 20 to 50 m. It is still a monoecious, deciduous and aromatic tree.
