QUESTION 1) The vocal properties of the shrieking eels of Florin are controlled by three genes. The dominant alleles, L (loudness), P (pitch) and T (timing) cause eels to emit loud, high-pitched shrieks in the morning. The recessive alleles (1, p, and t) cause eels to sing softly, at a low pitch, in the evening. In a three-point linkage analysis experiment, I carried out a test cross using a triply heterozygous eel and a triple recessive partner. When the eggs hatched, I found that the resulting 8000 offspring had the following phenotypes i) Loud, high pitch, morning 160 ii) Loud, high pitch, evening 690 iii) Loud, low pitch, evening 3000 iv) Loud, low pitch, morning 10 v) Quiet, high pitch, morning 3360 vi) Quiet, high pitch, evening 30 vii) Quiet, low pitch, evening 240 viii) Quiet, low pitch, morning 510 Calculate and draw the genetic map for the genes L, P and T including distances.
