Question

Review 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 at allele in the mother is required for proper wing development in the offspring. Submit Previous Answers Correct 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). For a maternal effect trait, an offspring's phenotype is determined by the mother's genotype. In this case, the genotype of individual 1's grandmother is not known; therefore, her mother's phenotype cannot be predicted. 1 2 v Part E a/a at/a What are all the possible genotypes for individual 2's mother?

Answer 1

Part E:
Answer: Option C is correct
Explanation:

WT dominant allele = a⁺

Mutant recessive allele = a

Maternal effect gene: If mother is affected, all her progeny are affected.
Individual 2 is affected. So, his mother must also be affected.
Genotype of the mother = a/a
