Consider a maize plant: Genotype C/cm ; Ac/Ac+ where cm is an unstable colorless allele caused by Ds insertion. What phenotypic ratios would be produced and in what proportions when this plant is crossed with a mutant c/c Ac+/Ac+? Assume that the Ac and c loci are unlinked, that the chromosome-breakage frequency is negligible, and the C allele encodes pigment production.

From a Drosophila testcross, the number of each phenotype obtained was as follows: W+ m f+ 218 W m+ f 236 W+ m+ f 168 W m f+ 178 W+ m f 95 W m+ f+ 101 W+ m+ f+ 3 W m f 1 Total, 1000 Construct a genetic map.

In the sample data from Sordaria shown in the picture: Count the total number of first and second segregations and calculate map units using equation below: (recombinant refers to second division segregation and non-recombinants are first division segregations)
