A) 2A + XX in one cell and 2A + X in the other
B) 2A + X in both the cells

Show Answer
Answer:
Correct Answer: A
Solution:
Gynandromorphs are formed due to misdivision of chromosomes and start as female with 2A + 2X chromosomes.
One of the x-chromosomes is lost during the division of the cell with the result that one of the daughter cells possesses 2A + 2X chromosomes and the other 2A + X.
