Plants - genetics

... For two alleles you have 1 : 2 : 1 For three alleles 1 : 3 : 3 : 1 For four 1 : 4 : 6 : 4 : 1 etc. So, if 4 in 1000 are 12 and 36 cm tall, that means that every in 250 plants is tall like that. And on which level of Pascal's triangle you have sum of 250? For two alleles: 1 + 2 + 1 = 4 For threee: ...
