A couple with STR genotypes (50, 75 ) and (50, 100 ) (where the allele numbers denote repeat length) have several children. What are the possible genotypes of their children for this STR locus?
What will be an ideal response?
As for any single-locus trait, simple Mendelian principles tell us what the genotypes may be: (50, 50 ) homozygote and (50, 100 ) and (75, 100 ) heterozygotes.
