This pedigree shows the inheritance pattern of a recessive maternal effect gene in Drosophila. In maternal effect, the offspring’s phenotype is under the control of nuclear gene products present in the mother's egg. In this example, the presence of the a + allele in the mother is required for proper wing development in the offspring. In the pedigree, individuals who are wingless are indicated by a shaded symbol. The phenotypes and genotypes are only provided for the first generation (individuals 1 and 2).What are all the possible genotypes for individual 1's mother? Select all that apply.
