HMX GENETICS EXAM QUESTIONS AND ANSWERS ALL CORRECT

Identical by descent - Answer regions inherited from same version of maternal chromosome. Will span a disease causing variant (Genetic) Linkage - Answer tendency of 2 genomic loci (variants or alleles) near each other on same chromosome to be inherited together. Is not binary. Determined in part by distance between 2 loci on same chromosomes
