Wоrldwide, оnly аbоut 35% of аdults cаn digest lactose, the primary sugar in milk. Breakdown of lactose requires the enzyme lactase; while it is normal for all mammals to express lactase as an infant, in most species, including humans, the gene is turned off at weaning. Thus, in most people, consumption of dairy products in adulthood is less than pleasant, a condition termed lactose intolerance. Lactose intolerance is caused by the non-persistence of lactase expression. The mutation that led to lactase-persistence (continued expression of lactase) is thought to have risen in frequency in pastoralist populations – those that started domesticating and farming animals. The image below shows regions of DNA around the lactase gene in African and European populations. The lactase persistence allele is shown in red. Each row is an individual and the colored bars indicate areas of homozygosity – a region where both chromosomes in one person are exactly the same sequence. These areas of homozygosity represent DNA sequences that are all inherited together without being split apart by recombination. What is the term for this?
