Three Loci,mitochondrial Malate Dehydrogenase That Forms a and B MDHa,MDHb

Multiple Choice

Three loci,mitochondrial malate dehydrogenase that forms a and b MDHa,MDHb ,glucuronidase that forms 1 and 2 GUS1,GUS2 ,and a histone gene that forms + and - H⁺,H^- ,are located on chromosome #7 in humans.Assume that the MDH locus is at position 35,GUS at position 45,and H at position 75.A female whose mother was homozygous for MDHa,GUS2,and H⁺ and whose father was homozygous for MDHb,GUS1,and H^- produces a sample of 1000 egg cells.Give the expected numbers of the MDHa GUS2 H^- cells she would produce.Assume no chromosomal interference.
