- You cross two wildtype (short-tailed) chipmunks, and collect a male offspring with a particularly long tail, which you name Dale. Tail length is controlled by the gene T, which is a maternally imprinted gene in chipmunks. Choose the best answers to complete the following statements. choose the correct answer option for each Dale’s allele for a long tail was inherited from the female/male/ unknown parent. That parent did not express the long tail phenotype because the allele was inherited from the parent’s own mother/father/unknown parent . If one of Dale’s offspring inherits the long tail allele from him, it will not /will/either will or will not express that phenotype.arrow_forwardSuppose that a Mendel's dihybrid cross between two double heterogotes (AaBb x AaBb) gave you the phenotypic ratio of 15:1, assuming that the dominant allele is completely dominant over the recessive allele.
