Three genes (a, b, and c) at three loci are being mapped in a particular species. each gene has two alleles, one of which results in a phenotype that is markedly different from the wild type. the unusual allele of gene a is inherited with the unusual allele of gene b or c about 50% of the time. however, the unusual alleles of genes b and c are inherited together 14.4% of the time. which of the following describes what is happening? a. the three genes are showing independent assortment. b. the three genes are showing independent assortment. c. gene a is linked but genes b and c are not. d. gene a is assorting independently of genes b and c, which are linked. e. gene a is located 14.4 map unites from genes b and c.`
