A wild legume with white flowers and long pods is crossed to one with purple flowers and short pods. The F1 offspring are allowed to self-fertilize, and the F2 generation has 301 long purple, 99 short purple, 612 long pink, 195 short pink, 295 long white, and 98 short white. How are these traits being inherited?

Answer: It focuses on one trait at a time

Explanation:

The flower ratio has a 1:2:1, this is implying that an incomplete dominance with PP = Purple, PW=Pink and WW = white.

The pod length has a ratio of 3:1 and this is implying that L or long allele is dominant over l or the short allele

The result will be

Flower color = incomplete dominance; Height = complete dominance
