- QUESTION 21 Which of the following can the results of a QTL tell you? a. The specific causative gene or genes underlying a trait you are studying. b. The heritability of your trait and how much the heritability is influenced by environment. c. Identify haplotypes associated with specific traits of interest in other populations. d. Identification of regions of the genome that are associated with a trait.Question 7 What pattern of expression would we expect if an organism is heterozygous for an incompletely dominant trait? both alleles are expressed, but only one really affects the phenotype only the dominant allele is expressed both alleles are expressed together in an intermediate phenotype O both alleles are expressed separatelyQUESTION 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 (I, 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.
