Answer:

b) 25% is the right answer

Explanation:

A woman  heterozygous for A blood group with genotype =  Iᵃi

A man  heterozygous for A with genotype =  Iᵇi

so after cross  between Iᵃ i   x  Iᵇ i

                      alleles            man                       woman

                                                                   Iᵃ                 i

                                                Iᵇ                  IᵃIᵇ              Iᵇi

                                                 i                   Iᵃi                 ii

so the offspring will be

                       25 % AB     IᵃIᵇ              25 % A     Iᵃi

                       25 % B     Iᵇi                   25 % O   ii

QveST [7]
The answers are A) ectoderm and B) endoderm.

Fertilization is a fusion of male and female gametes which leads to the formation of a zygote. The zygote undergoes mitosis and transforms into a single-layered blastula. Gastrulation is a transformation of the blastula into a two-layer or three-layer gastrula. Cnidarians are a diploblastic animal because their gastrula has only two layers - endoderm and ectoderm.
