🇬🇧
/ˌɔːtəʊˌtɛtrəˈplɔɪd/
four self-derived chromosome sets
Etymology
'autotetraploid' originates from Greek-derived combining forms: 'auto-' (from Greek 'autos', meaning 'self'), 'tetra-' (from Greek 'tetra', meaning 'four'), and the combining element '-ploid' (from New Latin/Greek roots used in biology to indicate 'fold' or 'form' as applied to chromosome sets).
'autotetraploid' was formed in modern scientific English by joining the elements 'auto-' + 'tetra-' + '-ploid' (following earlier formations such as 'tetraploid' and 'polyploid') and came into use in 20th-century genetics and cytology.
Initially the components carried general senses of 'self' and 'fourfold'; over time the compound came to mean specifically 'having four chromosome sets derived from the same species' in biological usage.
