In vitro model of species-specific binding shows in figure. Add the bindin particles to a plastic well containing a suspension of eggs. After 2–5 minutes of gentle shaking, the wells were photographed.

According to this figure, which of the following conclusion correctly define the phenomenon of species specificity?

#Unit 5. Developmental Biology

Figure a and d shows bindin bound to and agglutinated eggs from its own and closely related species.
Figure a and c shows no agglutination means bindin particles do not interact with eggs fom different species.
Figure b and c shows no agglutination means in vitro bindin particles do not perform species specific binding.
Figure a and d shows Each bindin bound to and agglutinated only eggs from its own species.
