The order and arrangement of genes in the heterozygous parent are
a. +++ / ops
b.
++s / po+
+++ / pos

e. both answers c and d are correct
the correct map of these three loci is:
a. p - 21cM - o - 14cM - s
S
b. s-14cM - o - 21 CM - p
c. s - 35.4CM - o - 14 cM - p
d. o - 14cm - p - 21cM s
e. both choices a and b are correct.
The single o-p crossover class is exhibited by the following offspring:
a. ++s=348; op+ = 306
b. p+s=96; +0+ = 110
