Imagine a Diploid Sexually Reproducing Organism, Diploidus Sexualis, That Contains

Imagine a diploid sexually reproducing organism, Diploidus sexualis, that contains three pairs of chromosomes.This organism is unusual in that no recombination between homologous chromosomes occurs during meiosis.
A.Assuming that the chromosomes are distributed independently during meiosis, how many different types of sperm or egg cells can a single individual of this species produce?
B.What is the likelihood that two siblings of this species will be genetically identical? You can assume that the homologous chromosomes of each parent are different from one another and from their counterparts in the other parent.
