You decide to study two species of birds, both of which form monogamous pairs (one male and one female). In species 1, you find
TEA [102]

In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.

  • This is because the species 2 are having many eggs.
  • These eggs were formed due to fertilization with multiple male bird partners.
  • As a result we can expect eggs with different genotypes.

Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts
