In a diploid plant, the three loci A/a, B/b and C/c are linked as follows A/a--------20m.u-----------B/b------------30 m.u.------------C/c One plant is available to you (name it the parental plant). It has the genotype Abc /aBC.
In a diploid plant, the three loci A/a, B/b and C/c are linked as follows
A/a--------20m.u-----------B/b------------30 m.u.------------C/c
One plant is available to you (name it the parental plant). It has the genotype Abc /aBC.
- Assuming no interference, if the plant is selfed, what proportion of the progeny will be of the genotype
- Again assuming no interference, if the parental plant is crossed with the abc/abc plant, what genotypic
