The bean seed is white and creamy, with white dominating over cream. they also have a flat and funnel shape, flat dominates over the funnel. Mom is white in color and flat in shape, and Dad is cream in color and funnel color. what will the first generation be like?

M – white
m – cream
T – flat
t – funnel
Based on the conditions of the problem, there can be two solutions: if the mother is homozygous or she will be heterozygous.
Р1: women. MMTT * husband. mmtt
gametes: MT; mt
F1: MmTt (white flat)
In the first case, all offspring will be of the same type – MMTt.
P2: female MmTt * husband. mmtt
gametes: MT MT MT MT; mt
F2: MmTt (white flat); mmTt (cream flat); Mmtt (white funnel); mmtt (cream funnel)
In the second case, 4 genotypes and phenotypes are distinguished in the offspring.
