Biology · Genetics
Chromosomal inversions are balanced rearrangements and thus do not change the overall amount of genetic material. While some inversions can exist in a homozygous condition, others only exist as heterozygotes because, in the latter condition, the inversion breakpoint disrupts:
- 1the pairing of homologous chromosomes during meiosis.
- 2a non-coding region of the genome.
- 3a coding region of a redundant pseudogene.
- 4a gene with an essential function.✓
Correct answer
a gene with an essential function.
