Solutions to sample midterm Mendelian problems
1) Because the father
all of his daughters
must inherit it. Because the mother is heterozygous, only half her sons will
2) Because B is
recessive to both the other alleles, only a BB
genotype will be Brown.
3) A cross
between two heterozygotes yields three genotypes (AA, Aa,
at each locus. Four such loci would yield 34 = 81 genotypic combinations, and so on.
