The FoxP2 gene is thought to be involved in language in humans. At prophase I, how many copies of the FoxP2 gene are present in a cell? Keep in mind that humans are diploid. 4 copies; 1 on each sister chromatid in a pair of homologous chromosomes 2 copies; 1 on each homologous chromosome 8 copies; 1 on each strand of each chromatid per homologous pair 8 copies; 1 on each sister chromatid in a pair of homologous chromosomes

Four copies, one on each sister chromatid in a pair of homologous chromosomes.

Explanation:

FoxP2 gene is involved in speech and development of an individual. FoxP2 gene encodes the FoxP2 protein and plays an important role in the process of communication.

The gene is diploid and contain two copies of each chromosome. At the prophase I, the four copies of the FOXP2 gene is present in the cell. The two chromosome contains four chormatids. All these four chromatids present the copy of a chromosome.

Thus, the correct answer is option (1).
