Maternal Effect

Distinguish between organelle heredity and maternal effect. Sort each property into the appropriate bin.• Exhibited by myoclonic epilepsy and ragged-red fiber disease (MERRF)• Exhibited by Leber's hereditary optic neuropathy (LHON)• The genotype of the female parent, not the genotype of the embryo determines the phenotype of the offspring.• Mitochondria and chloroplasts are responsible for the inheritance pattern.• The genetic products are distributed among newly formed cells and influence the patterns or traits established during early development.• Exhibited by Kearns-Sayre syndrome (KSS)• The effect persists for one generation only.

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 the female indicated by the “?” in the pedigree? Select all that apply.a) a+/a+ b) a+/a c) a/a What is the phenotype of the female indicated by the"?" in the pedigree? a) wingless b) wild typec)  50% chance wingless: 50% chance wild type
