Quizplus · Accepted Answer

Genetic imprinting is a mechanism in which genes have been modified in one of the parents and have differing effects depending on whether they are transmitted to the offspring through the egg or sperm. This is because certain genes are turned off or silenced in the egg or sperm by a chemical modification process called methylation. The resulting expression of the genes in the offspring depends on which parent contributed the modified gene. Polygenic inheritance refers to the inheritance of traits that are controlled by more than one gene. Genetic transmission refers to the passing on of genes from one generation to the next. X-linked disease refers to genetic disorders that are caused by mutations in genes on the X chromosome.
