The correct answer is:
S phase
Explanation:
S phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Accurate and accurate DNA replication is needed to counter genetic exceptions which often lead to cell death or disease. DNA replication occurs during this S (synthesis) phase. Gap 2 (G2): During the gap between DNA structure and mitosis, the cell will remain to grow and design new proteins.

Answer:
c. 28
Explanation:
Plant A has a dipoid chromosome number of 12, so its gametes will have an haploid number of 6 chromosomes.
Plant B has a dipoid chromosome number of 16, so its gametes will have an haploid number of 8 chromosomes.
<h2><u>Plant A</u> <u>Plant B</u></h2><h2>2n = 12 2n = 16</h2><h2> n = 6 n = 8</h2><h2 />
The new species C arises as an allopolyploid from A and B. An allopolyploid usually originates from the breeding of two different species.
In this case, <u>a gamete from plant A combines with a gamete from plant B to form a hybrid with 14 chromosomes</u> (6 from A and 8 from B). These chromosomes are unpaired, so the hybrid is sterile.
In order to become a fertile diploid individual of species C, the most common mechanism is polyploidization, where the genome duplicates. <u>That way, the resulting plant C has a diploid number of 14 x 2 = 28 chromosomes</u>, of which 12 are A and 16 are B.
