Anderson, L. and K. Sandberg, 1982. A linkage group composed of three coat color genes and three serum protein loci in horses. Journal of Heredity 73:91.

Anderson and Sandberg, 1982 published results on linkage studies for coat color and serum protein loci.

The number of progeny resulting from the four possible sire gametes were:

What is the percent recombination between these two loci? (To the nearest thousandth)

B) They also summarized 91 progeny from 7 stallions, each with the genotype, AlAAlBEe. In all sires AlAE and AlBe were linked together on the same chromosome.

This extension locus, E, has the allele e that when homozygous ee produces chestnut. The genotypes EE and Ee are black.

The distribution of the 91 progeny was :

What is the recombination frequency between the serum albumen locus and the extension locus? (To the nearest thousandth)
