Document Summary
All linked genes are syntonic but not all syntonic genes are linked. Ad bb ( a- blab ) adbb lablab ) Recombination and independent comes from assortment crossing over. Lingen : ad bb ( ab 1a b) x f. Aabb dabb ( a blab ) and bb x a abb. 20 syntenice linked the map oh distance if : The a and b genes are 20 map units apart. From a test ross of an ab/ab individual, what. 0 fraction of the progeny will be phenotypically ab? recombinant. The pair wise map distances for four linked genes are: b-d=21, c-d=5, a-c=8, a-d=3 and. An individual of the genotype aabb is testcrossed and the phenotypic distribution is not as expected for unlinked genes. Ab - 25 ab - 17 ab - 23 ( 812=64/25 ( 212=4/25 ( 1012--100/25 freedom = 70005 therefore happened unlinked could result this from sampling genes error.
