Question

question 5
which of the following statements regarding genes is not true?
genes consist of a long sequence of dna.
genes are the basic unit of information affecting a genetic trait.
genes are located on chromosomes.
in sexually reproducing species, each cell contains a single copy of every gene.

Explanation:

Genes are segments of DNA (so "Genes consist of a long sequence of DNA" is true). They are the basic unit of hereditary information affecting traits (so "Genes are the basic unit of information affecting a genetic trait" is true). Genes are located on chromosomes (so "Genes are located on chromosomes" is true). In sexually - reproducing species, most somatic cells are diploid, meaning they have two copies of each gene (one from each parent). Only gametes (sperm and egg cells) have a single copy of each gene. So the statement "In sexually reproducing species, each cell contains a single copy of every gene" is not true.

Answer:

In sexually reproducing species, each cell contains a single copy of every gene.
