In the two experiments described below, reciprocal crosses produce different patterns of phenotypes in the offspring. For each experiment, infer the correct genetic model.
A. True breeding strains of Drosophila are used in the following crosses:
Female ebony x male wildtype --> F1: all ebony
Female wildtype x male ebony --> F1: ebony females, wildtype males
The ebony phenotype is associated with a [ Select ] ["cytoplasmic inherited allele", "autosomal recessive allele", "autosomal dominant allele", "sex-chromosome linked dominant allele", "sex-chromosome linked recessive allele"]
