A homozygous recessive yellow-bodied, echinus, white-eyed female (y ec w / y ec w, the gene order is arbitrary) was mated to a normal male, and the resulting F1 females were mated to homozygous recessive males. After collecting 1000 F2 progeny, the following numbers were observed with each phenotype: + + + 475 y ec w 469 y + + 8 + ec w 7 y + w 18 + ec + 23 + + w 0 y ec + 0 Determine the order of the three loci and estimate the distance between them on the linkage map X chromosomes. Please explain in great detail how they got the number 475, ect and how they know they are female or male. • Show less
