What is the estimated number of genes in diploid cells of mice?

The correct answer is that the estimated number of genes in diploid cells of mice is approximately 30,000. This number is based on genomic studies of the mouse genome, which has revealed that mice possess a substantial number of genes that encode proteins and play various roles in biological processes.

Mice are often used as model organisms in scientific research, and having a well-characterized genome allows researchers to study genetic functions, genetic diseases, and developmental biology, among other topics. A genome with around 30,000 protein-coding genes indicates a complexity that supports the diverse biological functions necessary for a multicellular organism like the mouse.

In the context of gene numbers, options suggesting 10,000, 50,000, or 70,000 are not supported by current genomic data for mice. This emphasizes the importance of accurate genomic information in laboratory settings, especially when manipulating or studying gene expression and function in various research scenarios.
