Definition: Relating to a method in electronics where two different frequencies are combined to create new frequencies, often used in radio and television technology.

Example: The heterodyne receiver improved the clarity of the radio signal.

Definition: To mix a radio wave with another wave of a different frequency to create a new frequency that is the sum or difference of the two original frequencies.

Example: The engineer decided to heterodyne the signals to improve the clarity of the transmission.

Definition: Referring to organisms that complete different stages of their life cycle on different hosts, which are often not related to each other.

Example: Some species of fungi are heteroecious, requiring multiple host plants to complete their life cycle.

Definition: A type of gamete that is different in structure or function from another gamete, typically referring to the smaller, mobile male gamete and the larger, non-mobile female gamete.

Example: In many species, the male and female gametes are heterogametes, with distinct roles in reproduction.

Definition: Relating to organisms that produce two different types of gametes, such as male humans who create sperm with either an X or a Y chromosome.

Example: In many species, males are heterogametic, producing two types of sperm cells.

Definition: The process in which an individual produces gametes that have different numbers of chromosomes, typically seen in one sex of a species.

Example: In some species, heterogamety leads to the production of male and female gametes with different genetic compositions.

Definition: Describing a type of reproduction that involves different types of gametes or the presence of both male and female reproductive structures.

Example: Many plants are heterogamous, having both male and female flowers on separate parts of the same plant.

Definition: The condition in which two different types of gametes, or reproductive cells, come together to create offspring, often differing in size and structure.

Example: Heterogamy is important in many species for promoting genetic diversity.

Definition: The quality or state of being made up of different parts or elements.

Example: The heterogeneity of the community made it a vibrant place to live.

Definition: Made up of different or diverse parts or elements; not uniform or similar.

Example: The committee was heterogeneous, with members from various backgrounds and expertise.

Definition: In a way that involves different kinds or types; not uniform or consistent.
