A(n) $\qquad$ is a unit of heredity that consists of a sequence of DNA on a chromosome
genome
homologous pair
amino acid
gene
Solution
The answer is the last one: gene.
Explanation for each option:
Genome: A genome is the complete set of DNA, including all of its genes, in an organism. It is not a single unit of heredity but rather the entire collection of genetic material.
Homologous pair: This refers to a pair of chromosomes, one from each parent, that have the same genes at the same loci but possibly different alleles. It is not a unit of heredity itself.
Amino acid: Amino acids are the building blocks of proteins. They are not units of heredity; rather, they are the products of gene expression.
Gene: A gene is a unit of heredity that consists of a sequence of DNA on a chromosome. It is responsible for the inheritance of specific traits and is the correct answer to the question.
In summary, a gene is the correct term for a unit of heredity consisting of a sequence of DNA on a chromosome.
