A modification of a gene or chromosome that occurs during gamete formation or early development that permanently alters the expression of that gene for the lifetime of the individual is called
A)maternal effect
B)epigenetic inheritance
C)epistasis
D)extranuclear inheritance
E)sex-linked inheritance

Question

Quizplus · Accepted Answer

This is referring to an epigenetic change, which can occur during gamete formation or early development and can permanently alter the expression of a gene without changing the underlying DNA sequence. This change can be heritable and can affect an individual's phenotype throughout their lifetime. Maternal effect refers to an influence that the mother's genes and/or environment have on the phenotype of her offspring, while epistasis refers to a phenomenon where the expression of one gene is influenced by another gene. Extranuclear inheritance refers to the inheritance of genetic material outside the cell nucleus, such as through mitochondrial DNA. Sex-linked inheritance refers to the inheritance of genes located on the sex chromosomes.
