In an autotetraploid organism, the gene controlling coat color is very near the centromere of the chromosome carrying it. The allele Y for the yellow coat is dominant to y for blue coat. A homozygous yellow autotetraploid strain is crossed with a homozygous blue autotetraploid strain. What types and proportions of gametes would the F1 be expected to produce if the Y locus were 40 or more map units from the centromere? Derive the expected F2 phenotypic ratio.
