WebCombining multiplexed mass spectrometry and a mouse population with a high level of natural genetic diversity, researchers at Harvard Medical School and The Jackson Laboratory can crack an outstanding question in biology and medicine: how genetic variants affect protein levels. WebStep 1: Calculate P for breed A. P = number of polymorphic gene loci ÷ total number of loci investigated. P = 59 ÷ 100. P = 0.59. Step 2: Calculate P for breed B. P = 87 ÷ 100. P = 0.87. Step 3: Determine if results support the statement. The older breed A has a lower P value than breed B. This suggests that it has lower genetic diversity which could be …
