Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Maternal-Effect Genes
Maternal-effect genes are genes expressed in the mother that influence the phenotype of her offspring, regardless of the offspring's own genotype. These genes are typically involved in early developmental processes, where the mother's mRNA and proteins are deposited in the egg. As a result, the phenotype of the offspring can be affected by the maternal genotype, even if the offspring carry different alleles.

Maternal Effect
Phenotype
Phenotype refers to the observable physical and biochemical characteristics of an organism, determined by both genetic makeup and environmental influences. In the context of maternal-effect mutations, the phenotype is specifically influenced by the maternal genotype, leading to traits that may not directly reflect the offspring's own genetic information. This can result in unique developmental outcomes based on maternal contributions.

Mutations and Phenotypes
Mutation Types
Mutations can be classified into various types, including point mutations, insertions, deletions, and maternal-effect mutations. Maternal-effect mutations specifically alter the maternal genes that produce mRNA or proteins affecting the offspring's development. Understanding these mutations is crucial for analyzing how maternal contributions can lead to specific phenotypic traits in the progeny, often independent of the offspring's own genetic variations.
