Define the term maternal effect genes, and explain why the protein products of some of these genes are called morphogens.
Genes come in pairs and are responsible for the inheritance and expression of the associated phenotypes. All the different cells of the body require to express genes necessary for them to function. This is determined by some chemical signals that ultimately result in switching on and off of the gene expression.

Solved in 2 steps
- Explain the mechanism of maternal effect inheritance at the molecular and cellular level.Explain why axis-determination is a crucial aspect of embryonic development. Explain how maternal-effect genes encode cytoplasmic factors that play a role in axis determination.Explain mRNA and protein products of maternal effect genes within the early embryo?
- Explain the unique features of Ig genes.Explain how maternal-effect genes encode cytoplasmic factors that play a role in axis determination.Describe three types of genetic changes that commonly convert aproto-oncogene to an oncogene. Explain how the genetic changesare expected to alter the activity of the gene product.
- Describe the relationship between homeotic genes in Drosophila and in mice.You examine a maternal effect protein that regulates cell division. Will a mutation in this gene display a defect in the mother with the mutation, or in her offspring who have not inherited the mutation?In genetic maternal effect, the phenotype of the individual is determined by which of these statements? A. The sex of the parent who transmits the gene B. The nuclear genotype of the maternal parent C. The sex of the individual with only one sex able to express the phenotype D. Cytoplasmic genes usually located in the mitochondria E. A combination of environmental factors and the genotype of the individual
- Suppose you are analyzing the DNA from the polar bodies formed during human oogenesis. If the woman who produced the oocyte has a mutation in a known disease gene, would analyzing the polar body DNA allow you to infer whether the mutation is present in the mature oocyte? Explain.“In an organism that reproduces asexually, there is no difference between a somatic cell mutation and a germ line mutation.” Is this statement true? Explain.When Dorsal is translated, it is found throughout the embryo, not just on the ventral or dorsal side. How can this protein act as a morphogen if it is located everywhere in the embryo?
