Explanation:
Hello!
From an AaBb genotype we can obtain four possible gametes AB, Ab, aB and ab. With the Punnett square we can observe the crossing. In the second Punnett square we can see the form A– B–
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
AB Ab aB ab
AB A-B- A-B- A-B- A-B-
Ab A-B- A-bb A-B- A-bb
aB A-B- A-B- aaB- aaB-
ab A-B- A-bb aaB- aabb
The genotypes of the form A– B–, A– bb and aa B– have triangular seed capsules (15 of 16), while the seed capsules of the aa bb genotypes are ovoid (1 of 16).
