Document Summary

The parents shape how the alleles are positioned on the chromosome. For example: aabb ab ab ab ab. It depends; you should either have the % or the numbers: three-point testcross. **large numbers give you a hint which one is the parental, small numbers give you a hint who is recombinant. Analyze the loci two at a time: g-a. Ga 427+5 = 432 ga 410+2 = 412. Ga 51+33 = 84 ga 42+30 = 72: g-b. Gb 427+33 = 460 gb 410+30 = 440. Gb 5+51 = 56 gb 2+42 = 44: a-b. Ab 5+30 = 35 ab 33+2 = 35. G-a recombination % (cid:2785)(cid:2781)+(cid:2784)(cid:2779) (cid:2778)(cid:2777)(cid:2777)(cid:2777) = (cid:2778)(cid:2782)(cid:2783)(cid:2778)(cid:2777)(cid:2777)(cid:2777)=(cid:2778)(cid:2782). (cid:2783) % (cid:1775) (cid:1815)(cid:1818) (cid:2778)(cid:2782). (cid:2783) (cid:1803) (cid:2782)(cid:2783)+(cid:2781)(cid:2781) (cid:2778)(cid:2777)(cid:2777)(cid:2777) = (cid:2778)(cid:2777)(cid:2777)(cid:2778)(cid:2777)(cid:2777)(cid:2777)=(cid:2778)(cid:2777)% (cid:1776) (cid:1815)(cid:1818) (cid:2778)(cid:2777) (cid:1803) (cid:2780)(cid:2782)+(cid:2780)(cid:2782) (cid:2778)(cid:2777)(cid:2777)(cid:2777) = (cid:2784)(cid:2777)(cid:2778)(cid:2777)(cid:2777)(cid:2777)=(cid:2784)% (cid:1775)(cid:1776) (cid:1815)(cid:1818) (cid:2784) (cid:1803) 10 + 7 15. 6 thus, ga is too small .
