Read the following scenario and, based on your understanding of ethnicity estimate calculations, answer the questions below:

Jake received the following ethnicity results from 23andMe:

Image of a histogram that depicts Jake’s Ethnicity Results in 23 chromosomes, with both copies of each chromosome (except X) shown. Key shows that Jake is 95.5% European, 3.1% East Asian & Native American, 0.8% Sub-Saharan African, 0.1% Middle Eastern & North African and 0.5% Unassigned. Percentages of ethnicities have been assigned colors, with each color indicating specific segments on Jake’s chromosomes

Jake’s father, Henry, received the following ethnicity results from 23andMe:

Image of a histogram that depicts Jake’s Father’s Ethnicity Results in 23 chromosomes, with both copies of each chromosome (except X) shown. Key shows that he is 100% European, <.1% East Asian & Native American, and < .1% Unassigned. Percentages of ethnicities have been assigned colors, with each color indicating specific segments on Jake’s Father’s chromosomes

  • Jake has always wondered whether Henry is really his biological father. Based only on these ethnicity results, without considering the relationship prediction or other factors, could Henry be Jake’s father? Why or why not? Explain your analysis in detail.
