A diheterozygous female Drosophila is crossed with a recessive male. In the offspring, AaBb – 49%, Aabb – 1%, aaBb – 1%, aabbb – 49% were obtained. How are genes located on a chromosome?
genes are inherited linked, i.e. are on the same chromosome. The clutch is incomplete, because there are crossover individuals that simultaneously carry the characteristics of a father and mother: 1% + 1% = 2%, which means that the distance between the genes is 2 Morganida.
