He solution of the problem
The roots of gigantism is responsible for a recessive gene – and that it is linked with the gene for green color of leaves (a dominant trait). Distance between genes – 20 Morgane. The giants crossed with purple leaves (recessive trait) and diheteropogon normal size with green leaves (obtained by crossing pure lines: giant with green leaves and Burgundy with the usual). What percentage of giants with green leaves was the result?
This:
aa – huge roots
AA, Aa – the usual root vegetables
bb – maroon leaves
BB, Bb – green leaves
Find:
