Front

Linkage

Back

Genes close together on same chromosome tend to be inherited together

Front

Maternal Effect

Back

When mothers genotype directly determines the offsprings phenotype for a trait

Front

Nurse Cells

Back

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

Front

Epigenetic Inheritance

Back

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

Front

Dosage Compensation

Back

Mechanisms that equalize expression of X-linked genes between sexes

Front

Barr Body

Back

Condensed inactivated X chromosome found in female somatic cells

Front

X-inactivation

Back

Process of silencing all but one X chromosome in females

Front

Lyon hypothesis

Back

X-Inactivation in female mammals occurs randomly during early development

Front

Pseudoautosomal genes

Back

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

Front

Genomic Imprinting

Back

Epigenetic mechanism causing mono allelic expression
