alleryThe specific fixed position occupied by a gene on a chromosome is known as its what?
ATelomere
BLocus
CCentromere
DChromomere
Answer & Solution
Correct answer: B. Locus
1. Each gene sits at a definite point on a chromosome.
2. This specific position is called the locus.
3. The telomere is the end of the chromosome, not a gene position, which rules out option A.
4. So the position is the locus, option B.
