Loss of function mutations in essential genes cause embryonic lethality in pigs - Fig 1

<p><b>A) Example of a carrier-by-carrier mating in Landrace.</b> CxC litters will result in a 1:2 genotype ratio instead of the normal 1:2:1 genotype ratio. <b>B) Fertility phenotypes for lethal recessives.</b> A significant reduction in total number born (TNB) is observed for CxC compared to CxNC matings. <b>C) Carrier frequency for lethal alleles in the period 2012–2018.</b> Figure shows relative stable carrier frequencies over a time period of 6 years (except for LA4).</p>
