The advent of the BovineSNP50 BeadChip (with approximately 55,000 Single Nucleotide Polymorphisms, SNP), has enabled both genome wide selection and genome wide association analysis for traits routinely recorded in the dairy industry. The former offers the possibility of increasing rates of improvement by 50%, the sort of increase that will be required if we are to be able to help feed a population of 9 billion people expected by 2050. Although this is a very exciting development more is potentially possible.

BovineSNP50 BeadChip（具有大约 55,000 个单核苷酸多态性，SNP）的出现，使得对乳制品行业中常规记录的性状进行全基因组选择和全基因组关联分析成为可能。前者提供了将改善率提高 50% 的可能性，如果我们要能够帮助养活预计到 2050 年的 90 亿人口，就需要这种提高。尽管这是一个非常令人兴奋的发展，但还有更多可能。
