The following gel patterns are that of DNA markers observed in parents (P1 and P2), F1 from a cross between them and doubled haploid progeny (panel A) or F2 progeny, derived from selfing of F1 (panels B and C).
A doubled haploid (DH) is a genotype formed when plants are developed from haploid cells which have undergone chromosome doubling.
Based on the pattern observed in the DH or F2 progeny identify which of the patterns ( A to C) are based on DNA markers that are allelic?
1
A only
2
B only
3
A and C
4
A and B
