In a longitudinal study, 100 children born on the same day were sampled in a population of interest, and genotyped at one locus that has two alleles, A1 and A2. The children were followed every seven years until adulthood. At the end of the study, 75 reproductive adults remained from the original cohort of 100 children.

Genotype	A1A1	A1A2	A2A2
Number of Children	48	36	16
Number of Adults	30	27	18

Based on the relative fitnesses: w11 = 0.556, w12 = 0.667, w22 = 1, does it look like natural selection is affecting viability from childhood to adult reproductive age in this population? If so, which type of selection is acting on this locus?
