The normal cloven-footed condition in swine is produced by the homozygous rececessive genotype mm. A mule-footed condition is produced by the dominant genotype M-. White coat color is governed by the dominant allele of another locus B and black by its recessive allele b. A white mule-footed sow (female) is mated to a black, cloven-footed boar (male) and produces several litters. Among 26 offspring produced by this mating, all were found to be white with mule feet.
a) What is the most probable genotype of the sow?
b)The next litter produced 8 white, mule-footed offspring and one white clove-footed pig. Now, what is the most probable genotype of the sow?
