Show transcribed image text Comparing and contrasting Y chromosomal DNA inheritance, mtDNA inheritance, and autosomal recessive inheritance The pedigree below combines the results of Parts A, B, and C. Note that the mtDNA variants are shown only for the females in this pedigree. Based on the inheritance patterns shown in this pedigree, select all of the true statements in the following list. The most recent common mtDNA and Y chromosomal DNA ancestors were one couple. Individual 1-3 did not contribute his Y chromosomal DNA to the most recent generation. The coalescence of Y chromosomal DNA to a common male ancestor in this pedigree indicates that he was the only man alive at this time. Individuals 1-3 and 1-4 did not contribute any genetic material to the most recent generation. Individual 1-4 did not contribute her mtDNA to the most recent generation. The coalescence of mtDNA to a common female ancestor in this pedigree indicates that she was the only woman alive at this time.
