A yeast transient diploid is produced of genotype A/a; D/d, with
the two gene loci on different chromosomes. if a single meiosis of
this transient diploid produces a tetrad which contains four
gametes with genotype A;D, A;d, a;D and a;d this is a sign of:

A) A crossover between one of the genes and the centromere

B) A crossover between the two genes

C) Nothing in particular, it is what we would expect from
independent assortment

D) A double cross over between the two genes

E) All of the above

Please explain as well, thanks
