Q2. The table shows concordance for height between monozygotic and dizygotic twin pairs from birth to the age of eight years. A concordance of 1 indicates that the twins are identical in height. (b) Age (c) Birth 3 months 6 months 12 months 24 months 3 years 5 years 8 years Concordance for height between monozygotic twin pairs dizygotic twin pairs of the same sex 0.62 0.78 0.80 0.86 0.89 0.93 0.94 0.94 0.79 0.72 0.67 0.66 0.54 0.56 (a) If height were entirely genetically controlled, what concordance would you expect between monozygotic twin pairs? Explain your answer. 0.51 0.49 Does data for eight-year-old twins suggest that height is largely controlled by genetic factors? Explain you answer. Suggest an explanation for the low concordance at birth for monozygotic twins.
