alleryA segment of DNA that is responsible for the inheritance of a particular phenotypic character is called what?
ACentromere
BSatellite
CHistone
DGene
Answer & Solution
Correct answer: D. Gene
1. Chromosomes are made of DNA, which carries the hereditary information.
2. A gene is defined as a segment of DNA responsible for inheriting a particular character.
3. The centromere is a structural region of the chromosome, not a unit of inheritance, which rules out option A.
4. So the segment of DNA is a gene, option D.
