Maternal Effects and Genetic Inheritance

Genes close together on same chromosome tend to be inherited together

When mothers genotype directly determines the offsprings phenotype for a trait

Maternal cells that provide mRNAs, proteins, and nutrients to developing eggs

Transmission of gene expression patterns (and thus phenotype)without changes in DNA sequence

Mechanisms that equalize expression of X-linked genes between sexes

Condensed inactivated X chromosome found in female somatic cells

Process of silencing all but one X chromosome in females

X-Inactivation in female mammals occurs randomly during early development

Gene on Sex chromosomes that are inherited like autosomal genes because they exist on both X and Y

Epigenetic mechanism causing mono allelic expression
