I do not get it can you explain any better
For the answer to the question above, <span>I assume you are referring to DNA replication which takes place in the synthesis (S) phase of the cell cycle shortly before G2. If that doesn't happen, the cell will not proceed to G2 and eventually mitosis, thus division will not complete. </span>The new cells would have an incorrect amount of chromosomes.
Ans. (B). XX, XY ,XX, XY ,XY, XX .
In pigs, the XY-sex determination system is found. According to this system, sex of the organisms can be determined by the presence of a pair of sex chromosomes.
Females have two X chromosomes (represented by XX), and known as homogametic sex, while males have one X and one Y chromosomes (represented by XY), and known as heterogametic sex.
Thus, the correct answer is option (B).
