Definition: Relating to something that is formed or occurs on or just beneath the surface of the earth.

Example: The geologist studied the epigene features of the landscape.

Definition: The process by which an organism develops from an egg or spore, involving the differentiation of unstructured cell masses into specialized organs and systems.

Example: The concept of epigenesis explains how complex organisms develop from simple beginnings.

Definition: Relating to changes in gene activity that do not involve alterations to the DNA sequence itself, often affecting how genes are expressed in an organism.

Example: The study of epigenetic factors has revealed how environmental influences can affect gene expression.

Definition: In a way that relates to the changes in gene expression that do not involve alterations to the underlying DNA sequence.

Example: The researchers studied how environmental factors can influence gene expression epigenetically.

Definition: The branch of biology that studies how genes are turned on or off and how these changes can be passed down to future generations without altering the DNA sequence.

Example: Researchers are exploring the role of epigenetics in how environmental factors can influence gene expression.

Definition: The external reproductive organ of female arachnids, which is involved in mating and reproduction.

Example: The epigyne is a crucial part of the female spider's anatomy, allowing for the reception of sperm during mating.

Definition: A part of the female reproductive system in certain arachnids, specifically the opening of the female genital organs.

Example: The scientist examined the epigynum to understand the reproductive behavior of the spider species.

Definition: A type of stereoisomer that differs from another isomer in the arrangement of groups around just one specific carbon atom that has four different groups attached to it.

Example: Glucose and galactose are epimers because they differ in the configuration around one carbon atom.

Definition: A part of an organism that is one of the segments along its body or structure, often found in animals and plants, such as segments of limbs or leaves.

Example: The epimere is important in the study of vertebrate anatomy as it helps to understand the segmentation of limbs.

Definition: Relating to a type of stereoisomer that differs in configuration at only one specific carbon atom.

Example: Glucose and galactose are epimeric sugars, differing only at one carbon atom.
