25) In most social insects, females (workers and queens) develop from fertilized eggs and are diploids, but males develop from unfertilized eggs and are haploid. Because of these, the workers are more related to their queen sisters than to their brothers. Now we know that workers can control the sex ratio among the larvae destined to be males or queens by withholding care from male larvae and by altering the proportion of female larvae that develop into queens versus workers. In a colony with a single queen (and effectively just one male mating with the queen), a worker's fitness is maximized by rearing young queens and males ratio, approximately by the ratio of relatedness to her full queen sisters, and to her brothers. in a A. 3:4 B. 1:1 11 C. 3:2 D. 2:1 E. 3:1
