Before oogenesis begins, the oogonium divides four times with incomplete cytokinesis, giving rise to 16 interconnected cells in drosophila. These 16 germline cells, along with a surrounding epithelial layer of somatic follicle cells, constitute the egg chamber in which the oocyte will develop. These germline cells include:

Both males and females of a fish species show variation in colour. A population of this species consists of 40% blue females, 20% red females, 20% blue males and 20% red males. A researcher catches one fish at random from this population. Given that a male fish is caught, the   probability that it is blue is (Use decimal notation, not fractions or percentage)
