The mini pedigree below illustrates a pair of expectant parents One of them is heterozygous for a dominant allele causing a fully penetrant autosomal trait filled square The other is unaffected and lacks the dominant allele open circle The unborn child of this couple is represented by the diamond the child s phenotype is not yet known A SNP locus 10 map units from the gene determining this trait has 3 alleles A G and C the genotype of each individual for this SNP is shown below their pedigree symbol If the G allele of the SNP locus is on the same chromosome as the dominant trait allele in the affected parent what is the probability that the child will eventually express the trait AG O 100 O 0 O 90 O 10 AC CC
