Meaning and Definition
A gamete (sex cell) that differs in size, form, or function from the gamete it fuses with during fertilization; the counterpart to an isogamete.
In biology, refers specifically to either of the two morphologically distinct types of gametes involved in sexual reproduction, typically classified as the larger, non-motile female gamete (ovum/egg) and the smaller, motile male gamete (spermatozoon/sperm). The concept is central to anisogamy and oogamy.

Frequently Asked Questions
No. 'Heterogamete' refers to a type of sex cell (sperm or egg). 'Heterozygote' refers to a diploid organism that has two different alleles for a particular gene.
No. Only in anisogamous and oogamous species are gametes heterogametes. In isogamous species, the gametes are identical in size and form (isogametes).
No, it is exclusively a noun. The related concepts are expressed with verbs like 'fuse', 'fertilize', or 'produce'.
It is most frequently encountered in evolutionary biology, genetics, developmental biology, and botany/zoolology texts discussing reproduction.

Mnemonic
Think: 'HETERO' means 'different' + 'GAMETE' means 'sex cell'. A heterogamete is a 'different sex cell' — like sperm and egg are different from each other.
Conceptual Metaphor
Specialized partners: Conceptualized as two complementary, specialized components (like a key and a lock, or a plug and socket) that must unite to create a new whole.
