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

  1. Figure a and d shows bindin bound to and agglutinated eggs from its own and closely related species.

  2. Figure a and c shows no agglutination means bindin particles do not interact with eggs fom different species.

  3. Figure b and c shows no agglutination means in vitro bindin particles do not perform species specific binding.

  4. Figure a and d shows Each bindin bound to and agglutinated only eggs from its own species.

Mendel crossed tall pea plants with dwarf ones. The F1 plants were all tall. When these F1 plants were selfed to produce F2 generation, he got a 3: 1 tall to dwarf ratio in the offspring. What is the probability that out of three plants (of F2 generation) picked up at random all three would be dwarf?
