Generally, Animals Build an Organism Using the Diploid Number of Chromosomes

Multiple Choice

Generally, animals build an organism using the diploid number of chromosomes. However, insects in the order of ants, wasps and bees can use a haploid-diploid system where adults of one sex are formed with a haploid number of chromosomes. This would mean that

B) a female could determine the sex of the offspring by fertilizing or not fertilizing an egg.
C) the males and females are not equally "related" to their mothers considering the proportion of genes held in common.
