>What I dont know is in this condition, with an adult possessing only one copy of a given gene and an empty spot where the other copy should be is this: Will all the offspring inherit the one functional copy of that gene, or is it possible that the parent can in fact pass along the empty spot, essentially passing no copy at all 50% of the time.
In Genetic Strains and Variants of the Laboratory Mouse, they list several deletions at the c (albino) locus that are passed along.
Trouble is, I would expect a cell with a normal gene and a deletion to produce melanin like a cell with a normal gene and an albino mutant gene. And a cell with a pair of deletions to not produce any melanin.
