When observing a bird skin cell in g2 under a microscope, you count 160 total chromatids. how many chromosomes does a male chicken have in its sperm cells?

When a cell is in G2 phase, it has already doubled in S phase its DNA, meaning that for each chromosome we have two chromatids - > 2n (number of chromosomes) * 2 (number of chromatids per chromosome) = number of chromatids.

If 160 is the number of chromatids on G2 phase of a chicken cell, it means that the cell has 80 chromosomes (2n), and after meiosis, process to form a sperm cell, will only have 40 chromosomes (n).
