Hence, the only problem due to which these two bird population were not breeding with each other was their distant location and habitat.

Location and habitat are characteristic of spatial distribution and hence they were separate because of spatial reproductive isolation

Hence, option D is correct

Vladimir79 [104]

A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
