In tomatoes, the genes B (high) and b (dwarf), C (round fruits) and c (pear-shaped fruits) are localized in one pair of homologous chromosomes. When crossing a diheterozygous plant with a homozygous recessive, the following splitting of the offspring by phenotype was obtained: tall with rounded fruits – 38, tall with pear-shaped fruits – 10, dwarf with rounded fruits – 10, dwarf with pear-shaped fruits – 42. Determine the distance between genes B and C.

The distance between genes B and C is 20 morganids (20% crossing over).
