Solved by a verified expert:Meiosis Question
There is a gene R on the long arm of the same chromosome as
the huntington gene.

(1) Draw a labelled diagram to show the chromatids of a
diploid cell at the end of anaphase 1 of meiosis, for a person who is
heterozygous for both characters.

(2) Draw a labelled diagram to show the product cells
derived from this cell at telophase 2 stage of meiosis, NO CROSSING OVER.

(3) State what difference there would be in the product
cells at telophase 2 of meiosis if there had been one crossing over position
halfway between the Huntington disease gene and the centromere.
