if a chiasma forms between the loci of genes A and B in in 20% of the tetrads of gametes expected to be Ab is:

If 20% of A = 50% of B, then what per cent of A is B?

If recombination frequency between AB genes a 20% and BC gene is 40% and interference is 30% in the case of double cross over than what will be coincidance under this condition ?

The genetic distance between genes A and B is 10 cm. An organism with Ab combination of the alleles is crossed with the organism with aB combination of alleles. What will be the percentage of the gametes with AB alleles combinatory by an F1 individual ?
