SOLVED:In corn (Zea mays), the genetic map of part of chromosome 4 is as follows, where w, s, and e represent recessive mutant alleles affecting the color and shape of the pollen: If the following cross is made 1 × w s e / w s e and the F1 is testcrossed with w s e / w s e, and if it is assumed that there is no interference on this region of the chromosome, what proportion of progeny will be of genotypes? 𝐚 · b. w s e 𝐜 . s e 𝐝 . w 𝐞* e
