You are studying ear shape in dogs (with XY se x determination) and cross a true-breeding pointed-ear female to a true-breeding floppy-ear male and collect all pointy-ear male and female offspring. Your colleague suspects that the two phenotypes may be caused by alleles of one X-linked gene. What sort of cross would you do to determine whether this is an X-linked trait? Name it and describe it.What offspring phenotypic ratio would you expect in that cross if the green allele is a dominant X-linked allele? Make sure to label your ratio with all relevant phenotypes.How would the result of your cross (from A) be different if the trait is autosomal

Question

You are studying ear shape in dogs (with XY se x determination) and cross a true-breeding pointed-ear female to a true-breeding floppy-ear male and collect all pointy-ear male and female offspring. Your colleague suspects that the two phenotypes may be caused by alleles of one X-linked gene.

What sort of cross would you do to determine whether this is an X-linked trait? Name it and describe it.
What offspring phenotypic ratio would you expect in that cross if the green allele is a dominant X-linked allele? Make sure to label your ratio with all relevant phenotypes.
How would the result of your cross (from A) be different if the trait is autosomal
