The fruit fly Drosophila melanogaster has a diploid number of 8. Excluding crossing-over, what is the probability that a fly will inherit ALL of its chromosomes from a single parent?

female fruit flies usually mate with more than one male drosophila. Probability of inheriting all chromosomes from a single parent is 100% becuase crossing over does not take place in male drosiphila.
