Certain genes have apparently unusual inheritance patterns. for instance, in the mouse autosomal gene h19, only the copy inherited from the mouse's mother is expressed. conversely, in the mouse autosomal gene igf2, only the copy inherited from the mouse's father is expressed. the consequence of this is that imprinted genes are expressed as if they were present in only one copy, even though there are two copies of each of these genes in each cell. what process or processes are responsible for this phenomenon?

epigenetic inheritance

Explanation:

This phenomenon is known as genomic imprinting. Epigenetic control and inheritance is the basis of genomic imprinting: DNA methylation and histone methylation lead to inactivation (silencing) of a certain genes. The epigenetic pattern is imprinted and maintained in parents.

As a consequence of genomic imprinting, specific genes from only one parent are expressed. This is different than Mendelian type of inheritance in which in diploid cell one gene is from father while another is from mother.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
