Identify the correct sequence of formation of germ cell with four chromosomes.
A. Meiosis II anaphase
B. Meiosis I anaphase
C. Germ cell
D. G2
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → D, B, A, C
This is meiosis in a cell with four chromosomes (two pairs of homologous chromosomes), followed from the end of interphase to the germ cells.
D. G2 — first. DNA has already been copied in the S phase. Each chromosome has two chromatids, and the cell is ready to enter meiosis.
B. Meiosis I anaphase — second. The two homologous chromosomes of each pair (the bivalent) separate and move to opposite poles. The chromatids stay together. This is the reduction division.
A. Meiosis II anaphase — third. The chromatids of each chromosome now separate and move to opposite poles.
C. Germ cell — last. Four germ cells are formed. Each has only two chromosomes, half the number of the parent cell.
