The position within the original arginine codon where the point mutation most likely occurred was the second nucleotide. In this case, the mutation was CGA >> CAA.
<h3>Mutations and codons</h3>
A mutation is any alteration in the nucleotide sequence of an organism.
A point mutation is a single base substitution that doesn't change the open reading frame of a given protein.
In this case, the CGA codon encodes for Arginine, whereas the CAA codon encodes for Glutamine, thereby the mutation likely occurred in the second base (C<u>G</u>A >> C<u>A</u>A)

Answer:
recombination and independent segregation of chromosomes during meiosis
Explanation:
Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:
1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.
2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).
I believe it’s c
Because we know that equilibrium is a state of REST or BALANCE due to equal action forces ,so you can conclude that the cells are RESTING and at BALANCE when the cell is staying the same size it’s keeping balance.
