Abstract: A method for analyzing a genome of a single cell is provided, and a kit is also provided. The method for analyzing the genome of the single cell may comprise separating and lysing the single cell to obtain a whole-genome DNA of the cell; subjecting the whole-genome DNA to a whole-genome amplification to obtain a whole-genome amplification product; performing a PCR amplification using the whole-genome amplification product as template and using housekeeping-gene-specific primers to detect the housekeeping gene of the whole-genome amplification product; and determining whether the whole genome amplification product meets a requirement for sequencing based on the detection result, wherein a uniform distribution of the amplification product in each chromosome is an indication of the amplification product meeting the requirement for sequencing.
