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.

Draw a labeled 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, and draw a labeled diagram to show the product cells derived from this cell at telophase 2 stage of meiosis, NO CROSSING OVER, 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.

The gene for Huntington's disease is on the short arm of chromosome 4. This problem is about a person who is heterozygous for this gene and for another gene (R) that is on the long arm of the ...

Solution Summary

The solution demonstrates what meiotic chromosomes would look like during anaphase and telophase for someone who is heterozygous for two genes.
