You discover a new allele of a gene important for tail formation in mice. WT mice have long tails, but mice heterozygous for the allele have short tails. When you cross two heterozygous mice together, you obtain a 2:1 ratio of short-tailed mice to long-tailed mice. None of the short-tailed progeny are homozygous. What type of allele results in short tails? A) dominant negative allele B) temperature-sensitive allele C) lethal allele D) partially dominant allele E) incompletely penetrant allele
