Yes, an individual is a heterozygote for each specific gene where they carry two different alleles. They can be heterozygous for many genes simultaneously.
It's a evolutionary biology concept where heterozygous individuals have greater fitness (survival/reproduction) than either type of homozygote, helping to maintain genetic variation (e.g., sickle cell trait in malaria-prone regions).
The main stress is on the third syllable: 'zygote'. UK: /ˌhet.ər.əʊˈzaɪ.ɡəʊt/. US: /ˌhet̬.ɚ.oʊˈzaɪ.ɡoʊt/. Remember 'HET-er-oh-ZY-goat'.
