Question

II Review a tla + 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. a tla a/a 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). Submit Previous Answers 1 2 Correct For a maternal effect trait, an offspring's phenotype is determined by the mother's genotype. Since individual 2 has a wingless phenotype, his mother must have an ala genotype. a/a at/a Part F ? What is the phenotype of individual 2's mother? wingless wild type need more information Submit Request Answer

Answer 1

Answer part F Need more information. 14 of at Explain = The Phenotype depends on the presence in mother's genotipe. We know the genotype of 1 individual 2's mother (ala), We want to know her phenotype. To know this info, we have to know the genotype of her mother. (individual 2's Maternal grandmother) We have have no way to find the genotype of grand mother. It could be atla or ala or at lat. So, more info is needed.
