A mutation in an autosomal gene, Tum, causes benign tumor in a dominant manner ( T and t are two alleles of the gene). A mutation in another autosomal gene Mat (alleles are M and m ) determines conversion of the benign tumours caused by the gene Tum to a metastatic one in a recessive manner. A couple, Mr. Y and Mrs. X, both heterozygous for the genes Tum and Mat, have a child together. Based on this information, choo
